hi, i have a tarlov cyst in my spinal canal. i have SEVERE pain in my tailbone, buttocks and legs. i am pretty much stuck to my bed. i cant get comfy or sleep. my doc has me on opana er 20mgs 2 times a day and 10mg of percocet for break through pain. somas and lyrica as well. none of these help this horrible pain. i was wondering if anyone can suggest some good meds that may help my pain. i cant urinate or defacate properly. my life has become a nightmare during these last 4 days that ive had these symptoms. id appreciate any advice. thank you.
