10 month old w/ fever. Help!

My 10 month old had a fever of 102.2. We went to the hospital & it went down but it's back up to 102.3. The people at the hospital didn't say anything except he may have a uti. Do you know any ways i could bring his fever down?? I've tried taking him a bath, gave him infants tylenol, & tried putting a cool rag on his head but he hates it & starts busting out in tears.
