Well, there’s a difference between a doctor who uses “only antibiotics” and who only uses pharmaceuticals. One antibiotic doesn’t get all forms, so they must use combinations and other things that are not necessarily antibiotics- antiparasite, anti fungal, off-label uses, etc. But those would be synthetic medications, not herbal or natural.
So yes, you can get well using only pharmaceuticals/ allopathic doctor. For now, I use pharmaceuticals and antibiotics for killing the infections, and natural supplements and herbs to manage symptoms and support my immune system.
