 [ Symptoms ] i am 21 not pregnant i have never had a normal menstrual cycle i have maybe 2 a year should i be concerned i have a 3 year old but i never had a normal period even before she was born i have not had a period now in almost 9 months should i get a doctor appointment [ Disease ] the most common cause of sore throat is a virus and most will last about a week unless of course you are developing a particularly nasty viral infection called mononucleosis mono if your sore throat does not resolve in a week your doctor should consider ordering a mono test ebv panel hopefully you had a culture done takes 2 3 days since rapid strep tests are not 100 accurate as far as what to do about your extreme pain i am at a loss since i really have no way of seeing your throat or review your medical history gargling with warm saline 14 tsp of table salt with 8 oz of warm water can help ibuprofen can help again it is not typical to have extreme pain with a simple viral sore throat so you may need to be re examined
