About 6months Ago My Then Dr. Took Me Off My

About 6months ago my then Dr. Took me off my thyroid medication and wouldn't refill it. I know nothing about medicine so I that the problem was taken care of. On February 15 I fell downstairs in our house , my son called 911 and I was rushed to emergency. The first thing I even remember is waking up about a week later in ICU and finding out the surgical team had to tear my legs apart. I've had at least ten surgeries up to April 13 I have scars on both sides of my legs and am in severe amount of pain but am having problems getting pain medications that I should have. What can I do to get these people to understand that I am in severe pain, they took tissue, nerves ,and muscles
I have tried Tylenol but have allergies to snails, catapulting, lyrica ,tramadol, amyltripiline, and other medications like those. I have drop foot and have a hard time getting around . Please give me some advice on how to get them to understand being in this much pain is not a life and if this was something I did because of negligence on my part, but
it falls on one of their family medicine doctors. I really could use some advice I've lost so far 4 months of my life, I'll never be able to wear shorts again, and have had more pain in the last 4 months than most people have in a entire lifetime.
