Swollen, Sore Joints. Red Spots Like Bug Bite On Legs Turning Into Bruised Lumps After Taking Cipro For Stomach Infection. Itchy New Rashes On Legs And Arms. Help

I was given Cipro xl 1000mg on April 3 for a possible stomach infection. I had severe stomach cramps and loose stools for 2 weeks prior. After taking one pill, legs started to beak out with spots like a bug bite. Within 8 hours the spots swelled and got big and red like a bee sting, and hurt the same. My legs also swelled. I went to emergency and was told to stop taking the cipro. By April 8, the joints in booth legs and ankles were swelling. I went to a local Dr. and he described Prednisone 5mg--2 tablets 3 times day for 3 day, then 2 tablets twice a day for 3 days, then 1 twice a day for 8 days. Today my joints are still sore and believe I have tendeitis in my right ankle and the spots on my legs are hard lumps turning into bruised areas. I am developing a new rash, on legs and arms which is very itchy
