With my knees, I can feel it behind the knee caps, if that makes sense. They also do a lot of clicking if I'm sitting with them bent, after running.
The capsules are really expensive, but they seem to be helping - although that could obviously be a placebo! And, alternatively, the increase in exercise could be strengthening my knees as well.
I found them in Boots. I was looking at all the supplements aimed at joint issues.
I have always had knee problems. As a little girl I used to get pains in my knees, which were always described/dismissed as 'growing pains'. I have had various tests for rheumatism/arthritis, which have been negative. And then, when I was pregnant, I realised I wasn't suffering any more - which led me to conclude that it was something to do with my ligaments, and specifically an inflammation of the ligaments. When you are pregnant, your body releases a hormone called relaxin, which softens/relaxes all your ligaments. This was a clue to me that the ligaments in my knees were somehow involved in the pain I had been suffering (on and off - I didn't have it all the time!).
And I realised it was an inflammation, because if I took paracetamol (as opposed to aspirin/ibuprofen) it didn't deal with the pain - paracetamol is not an anti-inflammatory drug.
So I concluded that my problems were down to inflamed ligaments. (Quite what would cause this, though, I have no idea!)
Anyway, at one point I started to take Glucosamine, as this is widely recommended for joint pain. But it only increased the frequency of my knee pain - and when I realised that I was having to take aspirin almost every day, it seemed to me that Glucosamine wasn't helping. So when I was looking at the joint care vitamins/supplements, I was trying to avoid this - and that was how I spotted the Regenovex. This supplement supposedly deals specifically with the synovial fluid - which makes sense to me, as - if anything - the knee pain does feel as if there's something missing, something 'dry' at the back of my knees.
