Just want to know if its normal to have swollen hands after hives.?

I was on a medication for a UTI last week sunday. I remember 2 years ago i had a UTI and i took medication and i was allergic to the Sulfur in it, so i broke out in hives and had to take Benadryl. My doctor gave me a different medicine this time, one without sulfur, called Microbid. I took it for the whole week and this tuesday i started to get hives on my elbow, fingers, wrist, hands, and knees. I took 1 tablet of benadryl 4 times that day. Yesterday, wednesday, the hives stopped but my hand and fingers started to swell up on my right hand. Today its my left hand as well. My right hand seems to be going down really slowly and i got a hive on my left ankle. Is it normal to swell after getting hives? I took Benadryl yesterday and today, but today i increased the dosage to 2 tablets instead of one. I just want to know if this is normal.
