I have a long and odd history with statins. When I was first prescribed them I had no problem for over a year, then the particular type of statin was changed for cost reasons. A month or so after taking the new type of statin I had a lot of problems. These were extreme enough for me to stop taking them and refusing to do so; the problems vanished.
I then had at least a decade of being badgered by different doctors to take them again and was even sacked by one specialist because of my resistance. About 5 years ago my partner developed a heart problem and was naturally prescribed statins. She didn't, and still doesn't, have any noticeable problems with them so I thought I'd give them another try. I did, with the ones that I had previously tolerated and the same problems came back. I am now taking a very low dose of a statin that is considered less good but I can at least tolerate with the only side effect being occasional pins and needles.
Most people have some side effects from statins but they are slight. If that's the case then they are worth it, I think. As with most things medical this is a personal thing. I depends upon your level of cholesterol and your tolerance of statins and you should decide but decide from a point of knowledge and experience not just resistance to the idea of taking more tablets. You can only know if statins affect to adversely if you take them.
If you refuse you will be challenged about this at every meeting with a doctor so you need to do your research and be ready to argue your case. The ones I take are Rosuvastatin which are considered old fashioned and not as good as the latest Flashy Floyd ones but they work sufficienly well for me and they keep the docs at bay. I don't personally approve of the way statins are prescribed like aspirin, and thereby hangs a tale, but that's a different thread.
