I have had a very sore throat only on my right side. when i swallow it really hurts and even when i don't swallow it burns. no cold of flu symptoms. ?

Infection: One side or both doesn't matter as far as diagnosis. The vast majority are from viruses. If concern for strep head to your doctor.

See your doc: For an evaluation when you can. If any breathing problems, get seen now.

Aphthous ulcers?: Aphthous ulcers (whitish, shallow ulders with red rims) are quite common during early/late adulthood. They can be quite painful. The exact cause is not known, but it is believed that an autoimmune process and/or viral infection is causing such. Treatment is usually controlling the symptoms, as they will resolve. Also, possible herpes stomatitis, thus consult doc if u r concerned. Good luck.
