My father have throat pain on right side and feel something is stuck when he swallows from last 7 months and also treated with medicine but not improvement have seen. The pain is mild and same as it was 7montus before. Gone for various checkup. Cbc barium swallow everything come normal except neck contrast which suggests for biopsy. So what should I do. Either go for biopsy or do medical treatment. Because I am afraid if the report of biopsy comes positive. I need some herbal ,homeopathic or ayurvedic treatment suggestions. Please help. Also he is a copd patient and had suffered with severe TB 2 years ago.
