Thats true about Aloe vera gel I use it for hive rashes I get... it soothes them..
I would have it looked at, sounds like the beginning of an infection, also, until you can see a doctor, try putting pure aloe vera gel on it, aloe is TERRIFIC for healing burns.
It may be a good idea to get it looked at.. it could be infected, have you tried putting an antibiotic cream on a band Aid on it .
