Hi & Welcome!, but as usual I'm sorry you had to join us with this.
I'll echo the the comments made by others on here, I had to go
through many types of treatments before ketamine would be "put
on the table" by my pain mgt. Dr.
It's on the table now, but I'm holding off because it's very cost prohibitive
& insurance won't cover any of it.
Like Lottie said maybe nerve blocks are worth trying first.
I've had over 25 of them now (over 1 1/2 yrs.) & they keep the pain
managed pretty well in combo with meds. The first 3-4 nerve blocks
were pretty dramatic improvement wise (that pretty much confirmed my
dx) but I've slowly hit a plateau since then.
Do be agressive like you are with P.T. but don't over do, it can be a set back.
FYI I don't post much b/c mine is in left hand & arm but I try to keep
up.
