Hey guys, i was cutting some arrowshafts on saturday morning and wasn't looking where i was reaching and got into some stinging nettles (Cnidoscolus stimulosus) Usually 10 mins later its over and it doesnt bother me ever again...so i walked around all proud and tuff thinking "yeah i will hold out 10mins...you aint gonne keep me down". yup 10 mins later it quit but ever since my arm has still been welted up and itchy. its tuesday now. never had them have any effects this long. i assume the spines are still in there, but its on my hair covered arm. i cant see them and dont know what else to do. I have been using a hydrocortizone cream....but it doesnt work. anyone ever have them aggravate you this long? and treatment ideas? i have 21 little welts itchin the crap outa me.
