hi there sorry my reply is a long one too
firstly you are not a hypocondriac i have recuring bouts of tonsilitus at regular intervals throught out the year (for last 14 months ive had 7 bouts ) i have had exactly the same symptoms as you the last 3 times i had it it is a very virrilant strain which causes the tonsils to become septic and requires a massivly larger dose of penicillin taken for a lot longer than normaly given.
it is vitaly important that you get to your dr as soon as you can as this can and most likely will develop into septicimia (which can be fatal)if it doesnt get treated quickly enough i had this the first time mine went septic and was hospitalised because i was on holiday, i wasnt sure what to do about seeing a dr where i was and left it too long in the end going to the ER of the local hospital as i couldnt walk and felt so ill i thought i was dying.
sorry i hope i havnt scared you i just wanted to share my story in the hope it helps you in some way
so in a nutshell get to a dr as soon as u can.
ohh and just out of intrest these type of infections usualy attack you worst when you are feeling low or under stress i noticed you said about your exams so its possible that the worry has added to the tonsilitus allowing it to get a bigger hold on you even without you realising that you were particulaly stressed about them.
good luck with your exams and i hope you are on the road to recovery very soon
