This is not a joke, I'm dealing with serious swelling of the scrotum and I'm unemployed?

Over the course of the last few days, the skin of my scrotum has become swollen and "spongy". A couple of friends to whom I mentioned this said that it might be related to hives or impetigo caused by stress from a recent move and dealing with trying to find a job. However, another "rash" has appeared on the right side of my face, distending my right ear. My ear and my crotch are both itchyand tender, with some clear fluid seepage from small pustules. My face isn't too bad, but it worries me. I've tried Hydrocortisone, but that didn't seem to help. I'm presently trying a combination of Benadryl and Calendula Gel (an herbal medicine that has helped with rashes before). Just started the Benadryl today, started the gel yesterday. The gel does seem to help relieve the itching.

My big question is, does anyone know of a free health clinic in the Nashua, NH area? Even though I'm seriously broke, I'd like to find some kind of medical professional with whom I can talk. Thanks for any help.
