<human>: Thank you; I tripped over a paving slab on 3rd May and fell forward flat on the ground, hitting my chin and my left knee particularly. The knee was never swollen but was very bruised. The leg was sore to walk on but gradually got better until last week when I had a difficult drive to work owing to heavy traffic. After that my knee became noticeably more sore (though not extreme pain) and since then it has got worse again. No muscular pain, swelling or bruising but it gets progressively painful if I try to walk and if I touch around (as opposed to upon) the kneecap it stings. I now can t really walk or drive and am off work. Apologies for the lengthy e-mail. I would appreciate your advice. F
