This is going to sound potty but one of the veins that was used a couple of times at the RBH for amino and pot is still really itchy. It is not the area outside its is an itchy vien. I don't know if it is because it is right on the knuckle but it is drving me mad. I don't think it actually tissued (had so many I lost count) I think it just fell out cos of where it was (knuckle of index finger). Is this common and anyone got any bright ideas for stopping this maddening itch.
