Sorry to hear of all of your painful conditions...I can relate to quite a few of them so my heart goes out to you. I have extended family in Mobile, Alabama (I live on the Gulf Coast of MS.) and my Uncle sees a Pain Management doctor in Baldwin County...I don't know the doctor's name though =( You could call around in that area and ask if they take medicaid, etc. My Uncle is a Vietnam Vet and he's on Social Security and Disability benefits...He lives on a VERY fixed income and he is also on Medicaid...I'm not sure if the place he goes to accepts Medicaid but it's worth a shot to at least call around in that area and ask. I'm sure they must accept it or he couldn't affort to go. Good Luck with everything and may your pain ease up some dear.
Keep your chin up
I hope this helps somewhat. Much Love & Peace to you, Sincerely, L.
