It is enough that I cannot open my mouth on my commute in some places, but I ended up with a couple of nasty bites on the inner part of my arm on Monday. Thought nothing of it. However, it had not gotten better the entire week, and after getting back yesterday from a long ride it was really red and swelling. Went to the pharmacist who said it was probably an allergic reaction to the bites (possibly wasp or bee), told me to put ice on it, and an allergy cream. First allergic reaction of my life!
