I think I've finally worked out why my knee is swollen , appears to be a quadricep strain 
http://www.sportsinjuryclinic.net/cyber ... strain.htm
Seems to be grade 2 .  
I reckon since I haven't been riding and only sitting on my arse to then being stood at work for hours on end its pulled it . had been taking ibuprofen and cocodamol but they might as well be lumps of sugar for all the good they do , I hadn't taken any kind of medication since I put my back out around 2003 so I'm surprised they have had no effect whatsoever .  Don't have much of a limp today so seems to be healing but I still can't bend it past 90degrees ; most worrying of all I used to have quite a large muscle there but no matter how much I tense my leg it seems to have disappeared  :shock: 
I think it'll be a while until I've got that back
