Chronic Pain Support Group

This support group is dedicated to those suffering from chronic pain. Discuss treatments that have worked for you, find advice for your specific experience, and find support. You're not...

I am so sorry to hear you have this terrible pain.
What did the docs say and what were the options for treatment?
I also work on my feet 9-17 hours per day... So I get it
If you have done all the tests, etc and no one can really see anything besides guessing - there is one more option.
I kind of have the same problem going on with my jaw. I had a crushed jaw, open fracture, multiple fragments. Had surgery and the guy did a shit job. Then the wound inside opened, he did another surgery. I developed osteomyelitis, he missed it. I had to seek help elsewhere and had 3 more surgeries to remove most of of the bone, 5 teeth, both plates and about 17 screws. I also ended up breaking my jaw again while I was eating one day.
This left me with some really bad consequences.
During my last surgery in 2013 they removed floating bone fragment and also decompressed my nerve. While it did not produce complete relief, I really helped.
If you had a lot of surgeries and inflammation, it is possible that you have a lot of scar tissue around the nerve and this is why the meds are not working.
There may be an option for micro neurosurgery. The doctors can actually go in with a microscope, look around and see what the problem is. This is done in large cities. My Ortho was going to refer me to NYC if my leg trauma did not improve to treat this very problem in my lower leg.
In your case, I would imagine they can do a block with sedation. They only gave me an option of intubation because it is in my face.
Has your Dr. ever suggested using one of the off-label meds that are now used for nerve pain, such as Cymbalta, Neurontin, Lyrica, etc.? One of these meds might give you far more control over the pain.
As far as the surgery goes, can one of the surgeons who claim it was botched job go in and fix whatever was messed up, or is that not an option for you?
