I've been with UPS for 6 years now, brand new driver and i'm seeming to have problems with my knees. I've been deployed 4 times to the middle east in the last 4 years and i'm sure wearing all that gear didn't help. The Doc said it's Patella Femoral Syndrome which is basically 'bone bruising' that often happens in laborers and sport players. Are there any other drivers out there that experienced knee pain when they first started? How did you deal with it?
