So every year around this time during winter I get sick. It has happened for 4 years in a row the same sickness usually in varying intensity. A really bad sore throat, intense muscle aches, and throat burning/pain. Last year it went away and came back 3 times for 3 months and lasted about 3 weeks. I could live with it if it wasnt for the fact that its during swim season so my speeds take a hit, im in 3 choirs so i kind of need my throat to not be dying. I dont believe swimming has an effect.
