Started with sore left hamstring. Initiated after massage day and persisted through winter break. Aggravated by 12 mile flat run and too much driving.
Tried to run through it upon return. Little success. Purhased new shoes and cut back on volume. As of Jan 20th, hamstring is recovering, but entire knee joint seems weak. Perhaps due to improper compensation. Most pain in tendons, on inner side of knee.
Feb 28th - Knees still seems weak. Very strange. Got a knee sleeve earlier this week, which seems to help.
Stopped being an issue after a sinus-enforced 7 month layoff.
