I took some antibiotics for a strep throat and immediately developed seborrheic dermatitis couple days later.I had other symptoms including heartburn,fungus on foot, nausea, metallic taste when eating and my thyroid became overactive. Now I believe this has to do with my gut but what exactly do you think happened? I dont know if it is candida or leaky gut, I dont think it is cause I think I would have more other symptoms but I cant test for it either way. I really need your help because I have no idea what exactly is going on but im pretty sure it has to do with the gut and the good bacteria going away. Im supplementing with probiotics but I just have no idea how to solve this issue that the antibiotics has caused to fix the seborrhea.
