I had an allergic reaction to doxycycline Saturday and was treated in the ER with epi, IV fluids, benadryl, steroids. When discharged, I was not given prescribed prednisone. So yesterday the reaction began again when IV steroids wore off. I was treated in urgent care, which sent me back to ER. I am now home, and took my first prednisone tablets this morning. I have been extremely weak, with a lot of facial muscle weakness and a sense of no feeling - like my whole face got Botox yet I can still move the muscle if I try. Headache is getting worse and walking is unsteady. Of course, I can't sleep. My airways are totally open, so I feel silly going to ER a third time. Should I just wait it out? Is this a side effect rather than allergic reaction?
