Hi,
I'm sorry to hear that you are allergic to antibiotics. That must be so hard to deal with. When my husband had lung cancer I tried to find natural remedies that might help with all of the side effects he had with medications etc. One thing I found in my research was that honey is a natural antibiotic. So he started taking a tablespoon of honey each day and also a tablespoon of molasses each day. The molasses was a home remedy that my mom gave me years ago when I was young. Both seemed to make his symptoms improve and he felt better after he took them.
Another thing that you might do is pray about your situation. After all, God made you and he can heal you. I'll say a prayer for you too.
I wish you the best.
