I am a 28 year old female I am taking ciprofloxacin 500mg since the 6th of December for a bladder infection. I have had a headache since I have started this medicine and gets worse when I stand. Two days ago I woke up with both of wrists hurting so bad it felt like they were going to fall off and they still feel that way. If I put any amount of weight on them it hurts. I wanted to know if I should be concerned or if its in my best interest to quit taking them. My bladder feels better so I figure it wouldn't hurt to quit them. I have other conditions I live with daily which is IC that I can not take medicine for because it makes my hair fall out as well as endometriosis and a B12 deficiancy my levels are at 200. Anything would help and I would be grateful.
