Mono can cause white spots on the throat, although more often strep throat causes this. A doctor should do a throat culture to make sure, as untreated step infections can cause serious problems.
It could be mono or it could be another infection such as strep throat. You should seek the advice of a medical professional who can appropriately diagnosis your illness and organize your treatment. A physician can give you a mono test for conclusive results and definitive testing prior to treatment.
In mom often the throat is sore and red, but often the tonsils have pustules (white spots) on them. Mono has several other symptoms including fatigue, fever, and swollen lymph glands. You should see your medical provider for a confirmation of your self-diagnosis.
White spots on the throat are usually caused by thrush, not mononucleosis. The only diagnostic test for mono is a known as a mono spot test, in which the blood is examined for the virus that causes mono - Epstein-Barr Virus. Symptoms of mono include fever, swollen neck glands, extreme fatigue, and a sore throat.
If swollen throat with white spots is noticed it may be mononucleosis. It also may be thrush which is a yeast infection of the mouth. It is common after antibiotic therapy.
