I just did a dumb thing- I used the trimmer to whack weeds while wearing a pair of shorts. The battery on this thing only lasts 15-20 mins. but before I was finished, I got areas of bumps that look (and feel) like mosquito bites, but I don't think they are. I don't think it is chiggers either. I would think mosquitos, but they are centralized areas on the backs of my legs and I didn't see any bugs around me. I have alcohol, witch hazel, lotion, peroxide, typical first aid stuff. Does anyone know what will relieve this itching?
