I only started taking percocet yesterday, after suffering for 4 days with severe pain. I had tried everything, NSAIDS, hot wet compresses, I went for massages 4 days in a row! I'm going to have to go back and get an MRI, but in the meantime, I need to take the percocets. I just don't know if I should continue taking the subs while I am on the percocet. I want off the subs really bad, but I only got 15 percs and I don't know how long it will take me to get another Dr appt.
