I was taking half a day, then one a day, then up to 6 a day. Then I started having awful side effects
. My back pain got worse, my tongue was swelling some, and had stomach pain too. Then I had my lumbar injection and the pain got worse. I am scared this is an allergic reaction. I had my lumbar steroid injection, and the pain got worse, so my Dr prescribed Tylenol 4. I haven't taken the Percocet in over a day now, as it has scared me. I took the Tylenol 4 only twice yesterday.
