I have been having a knee pain since last 4 months.It has aggravated in the past few weeks,especially while doing squats and climbing stairs.Sometimes it's manageable but at others it is a searing or cutting pain around the knee.The bone just beneath the knee hurts the most,though I can't pinpoint a particular point.I can walk for long at times without hurting but bending and climbing hurts. I am 23,Male.Kindly suggest a remedy!
