I was prescribed DOXY for bronchitis. I'm on day 3 of the meds, 2x100mg per day. Within hours of taking a pill, the left side of my torso experiences sharp pains, I get a cold feeling all over and begin to sweat. I have felt somewhat disconnected and have a hard time concentrating on anything for a long period of time. I feel tired and dizzy a lot of the time. I'm really concerned about the pains in my left side, lower ribcage. I will contact my physician tomorrow if this continues.
