hello and welcome to HCM,
I have understood your concern about the swelling and pain which your husband is suffering.
You may be having an acute episode of tonsillitis
which has to be treated properly so that you can have good relief:
1. I would routinely perform a throat swab for proper treatment and management.
2. I would also advice you to take injectable medication which can give you faster and better symptom control
3. I would also start on an anti reflux medication
for proper control
4. If you are getting recurrent infections and the tonsils are enlarged then you may consider tonsillectomy
for better relief
take care and avoid cold drinks
