Hi,
Noted the history about having taken Penicillin for
tonsillitis that settled but pain and swelling remained, there is also sleep disturbance and feels that back of nose is congested.
All your history is suggestive that your treatment is still incomplete.
Continue the anti-inflammatory medicines along with a PPI like
Omeprazole to have complete reduction in size of tonsils to normal.
Consult an ENT SUrgeon for proper clinical evaluation, examination, investigations and evaluation of sleep disturbance.
If the medicines fail to reduce the size of tonsils then it is better to go for surgical removal as this may help for sleep disturbance.
Povidone iodine gargles.
Further management as would be suggested by your ENT Surgeon.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
