romanticqueen, I am allergic to cephalexin, clindamycin, gentamicin and some of the other derivatives within that family, however, their are many others close to this family but slightly different that I can take. It is really important that you try what he has offered you as you may be surprised how much an antibiotic can help you especially if this is a bacterial skin infection, you may want to seriously reconsider trying it (try it cautiously, take your first one early in the morning when you know people will be around and tell somebody you are taking it, if you notice any side effects ,write them down, if your breathing is affected, go to the e.r. immediately, itching and hives usually are the worse and go away pretty quick when you don't take anymore.
Also, it is VERY, VERY important with people like us who have allergies to antibiotics that you do find an antibiotic that you body can tolerate NOW before you SERIOUSLY NEED one for something else that may be life threatening, you need to know what antibiotic you can handle..... this is very very important
If this is not a bacteria attacking you , then it shouldn't change the problem and he can proceed from there. Watch for side effects, most are not life threatening in the real first line of base proscribed antibiotics, with most allergic reaction localized to skin itching, etc, but at least then you can mark this med off and try something else, again, as my doctor told me today, sometimes a diagnoses comes more from what they can't diagnose as to what they can.
Good luck, and don't give up, all you have is time, but the longer you wait to start trying to narrow down a diagnoses, the longer you wait to start marking off what it isn't, the further away from a specialist you become. I will be thinking of you and sending you best wishes, your not alone.

p.s. we have been conditioned by the media in the recent years to not take antibiotics (the whole, antibiotics make it easier for germs to mutate and become stronger issue), however, the reality is, that mutations lean more towards virus' than bacteria's and most skin ailments that don't put you immediately in to a hospital are bacterial and antibiotics still seem to work very efficiently in killing them.
