Hello, I was diagnosed with (oral) syphilis back in May. I was immediately treated with two doses of penicillin, which has destroyed the infection. However, my symptoms have never gone away. I still have a swollen lymph node on my neck and my tonsils/tongue are very swollen and are not responding to any treatment: amoxicillin, cephalexin, prednisone, or ibuprofen. My throat has been this way for 6 months now and won't go away. I have also developed bumps on my tongue AFTER treatment. Is this a new infection? Where do I go from here? My doctor is having a tough time helping me. Is there anything at home I can try?
