    Trapped Nerve - Very Likely the Cause of the Pain!!!!

    Symptom:
    Electrical shock  - Sharp Excruciating Pain - being cut by a razor blade
    This pain is most commonly associated with a "trapped", "choked" or "pinched" nerve.

    Nerve that appears to be affected:
    Sciatic Nerve leaves the spinal colom at L4 L5.
    Then passes through the Glutes (butt muscles) on the way to the leg.
    When passing through the glutes it goes under (in 15% of Pop through) the Piriformis muscle.
    The Infrapatellar branch, of the Saphenous nerve, branches further and crosses the patella.
    This is the site of the electrical shock / razor blade pain common to many of the forum posts.


    Possible Causes:
         • Swelling or inflammation of Piriformis muscle can cause this entrapment.
         • In 15% of the population the sciatic never goes through the Piriformis muscle rather than under it. This is called Pirformis Sydrome.


    Pippa Tried the Pirformis Streches in the Video.
    The result she went from having 0-2 attacks a day to have over 8 the following two days (and counting)!
    Stretching wasn't helpful - BUT it definitely points to this being the cuase of the pain.

    Not ACL, MCL, LCL

    MRI has ruled out any tears of any of her ligaments in the knee. Furthermore, these all result in instability of the knee and continuous pain. I've torn ACLs in both knees and 100% tear of ACL and MCL in my right knee. The pain and symptoms are nothing like what Pippa describes.

Pippa Tried these first.  Stretching and Exercising seemed to rally aggravate the Problem. It wasn't until she got the Cortisone shot that things started to improve.
Once things got better an on going program of exercise has kept the problem from recurring.

Update - Cortisone and exercise works!

She did the Cortisone shot. This gave immediate relief! And because she wasn't stressed about shocking pain out of no where she got back into her usual stretching and exercise routine. She's been pain free for months now 7/1/12. Seems like this works! Note: you may have quite a time convincing your doctor. This is a VERY rare condition which they will likely never have seen. Pippa's orthepedic surgeon was only willing to try it because we had exhausted all other possibilities. Still he didn't think it would do any good. IT DID!

10-8-12  I am so happy to report that I have my life back.  I'm not crying every few days.  I'm not in physical pain.  I am exercising, stretching and have not had any attacks since a few days prior to the injection.  Doctor didn't think it would work and he thought I'd have to have repeat injections- I haven't, but at least know that if I did have an attack, that this works for several months if not years.  GOODLUCK to you all!Pippa

Cortisone shots to the Piriformis Muscle appear to relieve the pain!

The problem is a trapped nerve in the Piriformis muscle. AKA Piriformis symdrome.
Pippa has tested this theory out by doing a lot of the stretches for the Piriformis muscle. The result - she went from having 0-2 attacks a day to having over 8. While stretches didn't help this definitely points to the Piriformis muscle being the Problem!

    Pippa Tried the Pirformis Streches in the Video.
    The result she went from having 0-2 attacks a day to have over 8 the following two days (and counting)!
    Stretching wasn't helpful - BUT it definitely points to this being the cuase of the pain.
