Since being diagnosed with fibro a couple of years ago, I've noticed that I am extremely sensitive to medications, especially antibiotics. I'm taking one right now for a UTI & it's not hitting me too hard, thankfully! I just feel really tired & a bit nauseated but not as bad as I have in the past. I found out the hard way that I am allergic to three different kinds of antibiotics, so bad that I had to go to the ER with breathing problems. So, now I'm scared silly to take one. Anyone else have problems taking new medications, feeling all of the side effects? It's a pain when I have to take something that makes me feel worse than before taking the meds.
