Recently on n off been getting a little bit of pain in my knee but this week its much more obvious, please tell me its nothing probably.

The pain is very localised immediately below my knee cap and above my shin, in a small thin area say an inch or two across. Pain is a burning kind. Can be after riding like it is now or during the day. Doesnt hurt at all while riding but is sore now after my ride an hour or so ago.

I also get a crackle noise when sitting down or going up n down stairs this does not hurt but is loud and seems to come from just above the same knee.

I ride flats and xc only so not a hardcore type of rider.

Sensible views?

infrapatellar bursitis?

I believe that if the pain such as you describe has no particular origin, then as suggested above it an inflammation of the tendons which should immediately be rested. As per the link a bag of frozen peas and ibuprofen complete the job.

Not sure why these issues flare up for no obvious reason, but there’s every chance that the above treatment a proper rest will cure it completely.
