Thanks for the query on HCM. What is your age & how was your childhood in terms of throat infections ? You should see a specialist ENT who can examine & check if you are developing an abscess
(pus collection) in/around tonsil
area. As per your description of severity of your symptoms, you need antibiotics which the doctor can prescribe after examination. Were you given antibiotics 2 weeks back, if yes, your doctor might give you 2nd level (higher/stronger) antibiotics this time.
You can try hot saline gargles (salt-water), but do visit a specialist quickly.
from HCM here can advise further.
Wish you get better soon!
