Back hurts. Kidney pain. Relief?

Went to the doc and they prescribed an antibiotic (Ciprofloxacin). I've had a UTI for almost 3 weeks. A few days ago (the 9th I think) I woke up with kidney pain (right side). Went to the doctor on the 11th. My back hurts so bad, it's almost intolerable. Also, feels like my lower right side of the front of my abdomen hurts too. Like a gassy feeling, but nothing passes. I'm a hypochondriac, with low pain tolerance. I feel like it's going to rupture. Felt like that last night too, but woke up this morning and it was gone. Now it's back. I know I can't have Ibuprofen, but can I still have Tylenol? Would IcyHot work? Hot baths and heating pads don't seem to work... I'm in so much pain, please help me? :'(
