Has anyone here had to take doxycycline and had a reaction to it? I had to start taking it in conjunction with Bactrim to help with the stubborn steno infection I had. However 4 or so days into taking the doxy, my tongue became "irritated" and sensitive to things I ate and drank. For example, I was trying to eat a pistachio/pineapple salad and I told my husband that it had a real bite to it, like it was tingly and burned a bit. He had some too and didn't know what I was talking about. Then the insides of my cheeks became inflamed and irritated and had that metallic-y taste. I have taken Bactrim before and never had those symptoms, but this is the first time I've take Doxy, so I knew that's what was causing it. I stopped taking it yesterday and today my mouth is already starting to feel better. Just curious whether anyone else has had trouble with Doxy.Thanks,Jen 34 w/cf
