I had an ACL repair approx. 10 years ago. I am now 52. Last week I went for my usual jog & the knee was sore, it feels sore inside. I ddnt go jogging today, as it doesn t feel right. I have taken anti-inflam & it seems slightly better. I do take USANA joint cartledge pills, over the counter pills from my physiotherapist. It is a dull ache which comes and goes, but I don t want to delay addressing it, as I do enjoy my running(7klm, 2-3 times a week). I went cycling yesterday and the ache was there then, but OK when I was walking around. I am not overweight, I eat well. Do I go to my GP or physio
