Hi there J,
Firstly let me say 'welcome to SkinCell'
It's always nice to hear from new members.
Well I'm sorry to hear about your troubles, it sounds like like they are a concern for you. My first reaction when I read your message was the same as the doctors, some form of insect bite seemed the most likely cause, but saying that I'm shocked to think that the skin trauma would last for this long, the healing provess should have kicked in by now and the welts should be almost gone, plis it seems weird that you would have 3 welts close together.
If they aren't then it really makes me wonder what else it might be. I guess it might be possible that the original problem was caused by some form of trauma like an insect bite
which then allowed the skin to become infected, which might help explain the itch/redness/discomfort when touched but it would be almost impossible to say without any proper examination of it by a professional Dermatologist.
Often doctors will not be aware of the million and one skin disorders or related problems that it might
be, they tens to deal with general health matters and so do not have the training.
As it has not gobe after this long and sounds like it may be infected I would certainly recommed that you drop in on a dermatologist as soon as your doctor can arrange it so you can have it properly checked and have your mind put at ease.
With luck it will just prove to be a mild infection that can be cleasred with a round on antibiotics.
