I just got put on steroids for my ears but I didn't read the instructions and I took ibuprofen after five steroids as instructed at 9.30am then I took four 200 mg ibuprofen at 12pm then another four ibuprofen at 4.30pm. I am in a lot of pain in my back and shoulder want it to stop. Did I take to much or am I just freaking my self out?
