chronic tonsillitis is a disease where there will be recurrent infection of lymphoid organs in our throat known as palatine tonsils.
in adult life these tonsils have no functions to perform and are not really requires for normal functioning of our body
you have to know that tonsillitis is not a absolute indication for tonsillectomy. decision to undergo surgery depends on patient who is suffering from the disease. if you feel that your problem is severe and interfering with your routine life then you have to decide on Surgery
without surgery or with surgery there are no long term consequences and undergoing surgery will not cause any problems in future, infact in cases of severe tonsillitis it will greatly improve quality of life
so if your symptoms are severe,recurrent you can undergo surgery, if you don't want surgery then it can be managed by taking antibiotics during acute episodes
Your fears were not unfounded. Even in the hands of an expert senior ENT Surgeon there have been rare bleeding complications leading to death too. This has led to utilisation of newer advancements in technology like LASERs and Cold Radiofrequency Ablation wands which I now use to do this surgery. This has not only made this surgery safe but also relatively painless and in adult males, I have also done it WITHOUT any ANAESTHESIA! (this was a time when there were a few anaesthesia related deaths in our city which the media blew up into a fear frenzy... So patient agreed to surgery only if it could be done without anaesthesia)
