i wish i knew more so i could help you.
i have some thoughts on your post.

i had severe pain issues too. i had several drs, all who had known me for yrs.
plus, i'm an RN and that should have made me a credible person. my neurologist had a Ph. D. in pharmacology and still wouldn't help me.

i found a pain dr thru a local rehab hospital. i just called and asked if they had a pain dr and got a referral. he really helped me a lot.

the other thought i have is to ask your local hospital if they have a diabetic class. sometimes listening to an instructor who's an expert can give you some other ideas to deal with the wt/diab.

now i shouldn't be the one to talk because i've been struggling with my wt and i have type 2.

stay in touch and let us know how you're doing. don't give up. help is out there.
