I did 4km on monday, most ive done and it was my 3rd run. I went out again last night, only did about 3km and my left knee was hurting on the side, today I can't put any pressure on my leg without it hurting, going up the stairs is abit tricky
Should I lay off the running for abit?
Also I had a virus about 4 weeks ago (cold & sore throat) I feel better but ive noticed after every run one of my ears feels blocked and my tonsil on that side really hurts, it keeps flaring up again. I went out last night running and today I feel awful, my head and ear really hurt. My ears do feel cold when I come in from a run.
Does running boost or lower the immunity? I feel so rundown at the moment but don't want to stop the running.
