I recently had a bladder infection and was given a form of Bactrim. I then started experiencing sharp, stabbing pains in my left leg almost every 10 min except when sleeping when it was more like once per hour. My doctor changed my meds to a different antibiotic (Ciprol?). The leg pains have decreased significantly, maybe every 4 hours - but now I am also experiencing numbness in my right hand middle finger. I feel like my vision may have been somewhat compromised but not sure if it is just that I am tired.
