I know exactly what you're dealing with, hun. I have reactive arthritis due to psoriasis, chronic migraines, peripheral neuropathy, & I'm at a very high risk for lupus/muliple sclerosis.
If you have the insurance, GET. TO. A. DOCTOR. You don't want to let it get worse. And diagnosis takes a hell of a long time, so you really need to start sooner rather than later. Pain medication is a sham, more often than not, ESPECIALLY if you have a chronic condition. It leads to addiction & it distracts from the source by concealing the symptoms... Locating the source & finding a treatment for it is your best chance at a good quality of life.
