I’ve either had an allergic reaction to something or some kind of insect bit on both my hands. I have these itchy, raised welts on some of the fingers. I immediately thought of bed bugs but I’m not itchy elsewhere on my body and I looked for them and didn’t find any evidence. Believe me, after my run in with bedbugs during grad school, I know what to look for and I haven’t seen any.
Difficult to tell what it is right now and I am hoping it’ll go away soon.
