Why is it that medical issues always come up on weekends when the only option is going to an overpriced and crowded urgent-care clinic? The wasp sting from three days ago has swollen to the size of my palm, is red and hard to the touch, and itches like crazy. I'm not in emergency phase. Right now I'm getting by on Benadryl and hydrocortisone cream, and I hope to hold out until Monday when I can go see my regular doctor. I've also had no appetite the past two days, and I'm wondering if that's related. I am mildly allergic to mosquito bites and bee stings, but I've never been stung by a wasp before. It is proving to be unpleasant.
