For the past 3 months I've been getting hives. I generally break out in the evening. Some of the welts fade overnight, but I wake up with new ones. After I get to work, they usually fade within a couple of hours. A couple of weeks ago, my upper lip started to swell, so I went to my doctor and he gave me a week's supply of prednisone (a corticosteroid), a couple of prescription antihistamines, and a referral to an allergist. I had to stop taking the antihistamines 5 days ago, in preparation for allergy tests tomorrow. I almost made it until then, but when I woke up this morning, my scrotum was swollen. It was a weird, but not unpleasant sensation. Even in a half-awake state, I was curiously aware of their size and weight, and how that caused them to move differently every time I changed positions. I even got a bit aroused, but was too sleepy to do anything about it. When I woke more fully and forced myself to get out of bed, I checked them more carefully. The swelling was in the scrotum, not the balls. In fact, my sack was so puffed up, I had trouble even finding them in there. Consequently, I couldn't feel the weight of my balls (as if they were floating inside the sack), but I felt the weight of the sack itself. As I said, it was a weird, but not unpleasant, sensation. As I got ready for work, my penis started to swell, too, but that wasn't as nice. The swelling wasn't in the erectile tissue like when you get an erection, but in the skin. It was soft and puffy and irregular and did not look at all good. Knowing that I had an appointment with an allergist tomorrow, I decided to just try to get through the day, so I put on some supportive boxer briefs and went to work. As the day progressed, my left cheek began to swell, and gradually moved to the right. By the time I left work, my upper lip was swollen. Now, at 9:00 p.m., the swelling has mostly moved to the right side of my face. As for my scrotum and penis, the swelling is now down, but far from gone. Hopefully I'll be back to normal by tomorrow or, if not, the allergist can give me something fast-acting. But I will kind of miss having a big ballsack.
