Backpain and burning skin

I'm a graduate student, and have been experiencing severe backpain and burning skin all over. I can't really sit down in class, and i'm not sure what to do about either symptom. My university won't get me lyrica because its not a generic drug. Does anyone have tips on hot to manage backpain and burning skin and also if you registered as a disabled student at your school? I dont know if I qualify since fibromyalgia doesn't impact me every single day.

You can ask for gabapentin. It's an older version of lyrica.
If you register as a disable person you need to get your doctor to back you up on it. You can also ask for tramadol.
