Lymphoid hyperplasia in my throat on one side. Tissue still not gone back to norm 4wk, antib, steroids how long should I give this and should I biopsy?

Unclear/need more in. The terminology you are using is not conventional. Do you have a lump or growth visible? If it is is a mass which is growing then a biopsy is indicated. Is it on your tonsil? A good ENT doctor is what you need to guide you further.
