Hello~It is probably just an infection of the tonsils, but to be safe, I would see your PCP, he/she will probably do a swab and send it to be analyzed, they can sometimes even tell by looking how serious the condition is. I wouldn't worry until you have something to worry about. :-)
You say you get sick often and don't heal well, hmmmm, have you been checked for diabetes? Quite possibly the low immune system from the low-grade infection in your tonsils could be causing both, but again, please get checked and let the doctor take it from there.
I hope you feel better soon. God bless you.
My niece had reoccurring tonsillitis until I gave her vitamin D gummies. Optimal vitamin D levels are 100 - 150 nmol/L (40 - 60 ng/L). When I had vitamin D deficiency I was sick all the time!
"CONCLUSIONS: Seventy-eight percent of Auckland children undergoing (adeno)tonsillectomy had a 25(OH) vitamin D level<75nmol/L, a level which is associated with an increased incidence of upper respiratory tract infection. Low 25(OH) vitamin D levels were related to a darker skin, increased BMI and larger assessed tonsil size.
The association of larger tonsil size with lower 25(OH) vitamin D status needs further evaluation but offers a potential explanation why black and Hispanic children are more likely than white children to have (adeno) tonsillectomy for snoring or obstructive sleep apnoea."*
