Thank you, tim1028, for your reply. I am doing all five of your recommendations. The daily baby aspirin is chewable, so less likely to damage digestive tract. I swim 1,250 yards at a fairly brisk pace 4-5 times per week and usually do something like walk at least once or twice additional. Hopefully, the vitamin K2 will slow or maybe reverse calcification. I feel a strong need to get rid of as much calcium as possible, so am looking into chelation. The propaganda that I have read so far indicates, while there is some risk, it is fairly minimal. Do you (or anyone else) have information to the contrary? Thank you in advance for your help.
