Hi!!! Wow - finally someone with the same problem as we have. My 17 year old son is allergic to every antibiotic there is - we have 1 left to try in case he gets something very bad. I also am allergic to almost all of them - hives, itching - we are scared to death for him. I take him to a great allergist and I even took him to an infectious disease specialist who basically was nice, but shrugged his shoulders. They have no idea why we are so allergic to just antibiotics. We can both take over the counter meds - my son has bad environmental allergies which he receives allergy shots for and is doing much better. Please email me!!! I would really like to talk to you. Just leave a note in the subject area of the email so I know it is from you because I won't know your email address. My name is MaryAnn - looking forward to hearing from you.
