I banged my leg into a metal child/dog gate when I was walking in the dark in the middle of the night. Then I went right back to bed. (I should have iced and walked more) A clot traveled to my lungs but was misdiagnosed as pneumonia. That was around 15 years ago and most of that time I was on a very high dose of warfarin (15 mg. per day). Except for one anesthesiologist who spoke to me before a knee replacement I had no knowledge that was an extremely high dose. After 2 recent vertebra fractures I learned Warfarin probably did a number on my bones--I now have severe osteoporosis. I am on the blood thinner Eloquis for about the last year or so--and doing BHRT and strontium citrate (along with the other recommended supplements) in the hope my bones will benefit. I am very fearful of the bone drugs. I am 83.
