Just below the knee I swell up. It gets worse as the day goes on. Can you tell me what it could be?

We can't diagnose I'm afraid but I wondered if it was aggravated on days you wear a heel or a wedge?

I'm also curious as to whether you are up and down stairs a lot during the day, as this would also place undue load on the patellar tendon beneath the knee, as would a sporting activity, which involves jumping.

Please ask the doctor to have a look but you can relieve the discomfort with Atrogel^®, applied morning, noon and night.

Please let me know of any further details you or your doctor can provide and I'll look at those specifically.

Best wishes

Earle
