If you feel suicidal, then go to an ER. Call the pm and see if you can get in sooner, they frequently have cancellations. You definitely need a psych evaluation asap, which will be covered by medicaid. The YMCA has sliding scale memberships--sometimes even free ones, which would get you into a warm pool.

Regarding meds, it is not uncommon at all to require opiates with RSD. I went without for years, and my quality of life is substantially better with meds that help lower my pain levels (it doesn't take it away). I've had RSD for 10+ years and recently tried Ketamine and feel it gives me the best hope for a decrease in symptoms. Everybody reacts differently to every med and treatment--and new ones are discovered every year.

Good luck.
