Hi Dayton,
It sounds like you have a really good doctor. If he is as cute as you proclaim, I'm catching the next plane

Is he a primary care physician or is he a specialist? If he is a specialist, what field is he in?
In reference to your questions numerically:
1. Regarding the baclofen, I don't think it is for weight loss but I haven't looked in to it further.
2. Regarding the tingling... Been there, heard that, not satisfied with the answer.
3. Oh wow, I can answer this one: Exercise to tolerance. If it hurts, cut back a bit or find another exercise for the time being that is not so harsh. If it is really painful to walk on your foot, try walking in a pool. You have to keep moving that foot.
4. Again, he sounds like a really good doctor when he considers your loss of sleep and cares to do something about it.
He also mentioned the burning pain, which is very interesting: Is it gone completely or tolerable,that is, without medications? And on a scale of 1 to 10, what is your lowest daily pain, your average daily pain and your highest daily pain?
I hope you have a good week. Please take care,
Norine
