I recently had 2 lumbar epidurals. I don't know what meds were used but the epidurals were 2 weeks apart. About 3 days after the 2nd epidural I began having rapid heart rate, which is still occurring. This is making me weak and if I try to do anything at all, including walking, I have to continually stop to slow my heart rate and catch my breath. The Doc at the Pain Center that administered the epidurals maintains this is not in any way related to the epidurals. My Primary Care Doctor, however, disagrees. He feels certain my problems are caused from the steriods in the epidurals, more than my system could tolerate that close together. My questions is... How long will the meds from the epidurals remain active in my body?
