Outer right knee pain with bony growth

[Gilley5]

I am a retired gent of 61 who walks about 5 to 7 kms every day. Over past few yrs I have developed a tight uncomfortable pain on the outer right knee, just to the right of the kneecap. A hard bony lump has developed over time as well, in the painful area. It looks quite exaggerated when compared with the left knee which is normal, with no pain. About 3 yrs ago I did have problem with what felt like a painful tightness behind the same knee, which became quite uncomfortable when going down on my haunches. It now seems to have moved to the ouside of the knee as described. The pain is not unbearable yet but is becoming more uncomfortable with time. I played a huge amount of squash when I was younger but not for the past 12 years. May have something to do with the problem.
Would be most grateful for  your input.

Doctors call the outside of the knee the lateral side of the knee. There are several common causes for pain in this area that vary by age and activity level. Once the source of the lateral knee pain is identified, it usually can be eliminated or decreased.

You have to take some rest and anti-inflammatory drugs. Ice packing would also help. If it does not decrease you have to go to an orthopaedician for examination of any ligament, tendon pronblem. Take care!
