Days in hospital symptoms and conditions

I am happy to find this site. I was given Levaquin for UTI. A few weeks prior to getting this prescription I was given a sulfa based drug (generic for Bactrim) and started feeling some pain in right wrist and hand. Dr. prescribed Levaquin since this sulfa based drug didn't clear up infection. Took 2 doses of 250mg and the reactions hit - both hands swelled, joints ached, both knees swelled and both feet and ankles swelled. Went to ER and admitted and spent 3 days in hospital on morphine and started prednisone treatment of 20mg a day with Aleve to also help with pain. This Levaquin is NASTY stuff. I can't believe doctors prescribe this medication. I am still not well. How long does it take to recover? I still am stiff and ache. I too am very active runner and finding myself frustrated in the slow recovery.
