The backmice.info project

I am Marta Cañis Parera. I am a medical doctor from nearby Barcelona. On February 2018, I started my Ph.D. studies about “fatty tissue and low back pain” in the Universitat Rovira i Virgili from Reus, Spain.

As part of my Ph.D. studies I am doing a bibliographic review about fatty tissue as a cause of low back pain. Within my thesis project I am under the construction of this web page called backmice.info, where I plan to share this bibliographic review (in 4 main chapters) and write a blog with my personal views  at the same time.

The aim of the backmice.info project is to share the information about this entity that still seems to be under-recognized by many doctors nowadays, and to make it a useful tool for me to share information with other researchers or people who may have a special interest in it.

  1. This website has been a Godsend! Thank you for all of your research and for posting it online for the benefit of everyone. I just had a back mouse removed today! I have many photos of the procedure if you’d like me to share those with you. My surgeon even admitted after researching this herself, she believes she has one too that has been misdiagnosed! It’s amazing that such a small piece of fat can wreak such havoc and that so many people are suffering due to this mostly unknown problem. Thanks again for all that you have done and are doing. You’ve definitely made a difference in my life. Keep up the great work!

  2. Hi Marta

    Thanks for the information on your site. It’s part of what helped me get answers for my cluneal nerve entrapment that I had suffered with for 3 years.

    I had surgery last week and I am feeling so much better after the removal of two episacral lipomas… one of them over 5x3x3cm

    I do have a quick question for you. In your literature review, have you come across any information on recovery time? I think I’ve had about an 80% reduction in pain. Have you read anything about the time it takes for the pain to resolve following surgery? Ie should I anticipate further resolution with healing and with the swelling going down etc.

    I am seeing my specialist next week for follow up I am just interested to hear about the literature.

    1. Hi Rachel,
      Thanks for writing.
      According to the articles some patients have immediate relief and some others take a while. Specially if there is a formation of a seroma or hematoma at the surgical side. Did they place any drainage to you? But I can’t tell you a specific recovery post-op time.

  3. Thanks so much Marta

    I certainly don’t have the qualifications to say what it is but there is certainly some type of swelling at the incision site. I think the fact that others have said it can take time makes me feel less worried. I just hope I continue to see improvement. It’s definately been significant to date.

    I am not sure of the medical terms but I have two lipomas one in each of the ‘dimples of venus’. The incision was above each lipoma.

    I did not have drains inserted.

    Thanks again Marta.

    Regards
    Rachel

  4. Hi thank you for this article. I fell in 2012 and been passes from one person to the next. Do I mention this to the pain clinic where I’ve had shots before, or my physician? Again, thank you. I have so many they almost run together from lower back down to sciatic and into hip where there is a large bursitis. We are moving and I’m bent over and everything gets hard and more pronounced as does the pain. Many thanks. Jina

    1. Hi Jina,
      Thanks for you message. I hope the web site can help you. Please always check with your doctors.

      Regards,

  5. For nearly a decade now I’ve been telling doctors and specialists that these knots on my lower back/hips/butt are excruciatingly painful, I have referred pain that basically from my waist down. And time and time again it’s been disregarded and I’ve been misdiagnosed. I finally feel vilified and I’m not crazy. Now to just find a dr that will listen and remove them so I can have a life again. They’re huge and debilitating. Thank you so much for this!! I finally feel like I have answers!!

    1. Hi Leona,
      I am a doctor myself and I was never thought about backmice during my career and during the past years. Last year after my husband had one I decided to search about the nodules. I think that we doctors many times still forget that there are still many fields in medicine to be studied, and sometimes we tend to dismiss patients opinion, unfortunately. I am trying to study and discover the scientific reasons why such a entity, backmice (that are mainly localized painful edema of the deep fatty tissue that cause peripheral neuropathy) can be so painful, patients can also help on that work by explaining to doctors that “want to listen” about it. In medicine we have neglected both things: the fatty tissue and the peripheral nerves as a main causative pain agents. If you need help tell me.
      Regards,
      Marta

    2. Leona – I have had 5 removed. I see a plastic surgeon. Try there. See one that is affiliated with an orthopedic practice and not one that is 100% cosmetic.

  6. Hello, I have been suffering from severe lower back pain in these areas for over 10 years. I had looked into what the lumps were several years ago and couldn’t find much information other than. Dr 1937 who discovered them. My question is would I need an orthopedic surgeon or general surgeon. I actually see my pcp tomorrow and will have her feel them . I do find when I’m confined to my chair at work for long periods without moving about seems to exacerbate pain to where it stiffens and doing any task such as sweeping, mopping . Bending over seems to really cause intense burning and throbbing. I will keep you posted. I’m so glad to have found other people that have had removal and 100 percent relief . My Fnp I see should be able to shoot me up with lidocaine to see if that provides any relief .
    Thank you so much for sharing your information and starting a place where to find help.

    1. Hello Tara,
      Thanks for writing.
      In Spain, as far as I know, nobody gets operated from backmice, but I would think it will be a GENERAL SURGEON matter. Maybe many patients get diagnosed just as a “lumbar painful lipoma” and some may be operated. According to the published articles many got relieved.

      The question is that nowadays most of the “LOW BACK PAIN” in medicine is categorized as “UNSPECIFIC LOW BACK PAIN”. Unspecific because MEDICINE DOES NOT HAVE YET AN EXPLANATION. SOMEHOW it seems that we paid little attention to the FATTY TISSUE as a causative agent (despite the great work of some authors like COPEMAN).

      Apparently the fatty tissue that provoques backmice tends to EDEMATIZE EASYLY and if the edema get confined or encapsulated it causes compression with local pain and even peripheral neuropathy (CLUNEAL NERVE NEUROPATHY in the lower back). Many causes have been described to cause this edematization and subsequent increase of pain: cold dampness, stress, hormones, too much resting or sitting, fever…

      Tell me If I can help you further,
      Marta
