Has anyone overcome the problem of needing anti-inflammatory medication but being prevented by being on blood thinners? Paracetamol just doesn't cut it for me now and I am getting such pain in my knees that I fear I am not exercising as I should to keep going (I mean just walking). If I have to make a choice - is there one? What risks would be involved? I am an 82 year old male and active up to six months ago.
