Bird, I suggest you read the fine print on possible side effects. The drug should have the makers test results from trials.
I'd be a little leery of reading unsubstantiated BS on the internet regarding any drug. I don't think there is a drug or food or anything that someone somewhere isn't making outrageous claims against.
There are responsible sites where your drug will have the real deal listed. All the statins I have read about have a warning against possible serious muscle damage with one of the symptoms being weakness.
I do believe statins are a good thing for many people trying to reduce cholesterol but not EVERYONE.
Regarding giving up diabetes meds. Probably a very bad idea if the diabetes is very serious at all. I have had lots of friends with diabetes and probably am as aware of its treatment as anyone who doesn't have it except for doctors of course.
There is virtually always a trade off when you take medicines or receive treatments or surgeries. You need to get all the facts available, including alternatives and decide in your situation what is better, treating the condition (and how) or not. There are lots of things that are serious, take prostate tumors/cancer for example. If the tumor is slow growing and the chance of it becoming life threatening during the reasonable life expectancy of the patient is sufficiently small then not treating it may be the clear best choice.
Just getting frustrated and going into denial and stopping all meds is usually NOT a good option. Medicine/medical treatment is not an all or nothing endeavor. Proper management will consider alternatives and degrees of treatment not just all or nothing.
I have had to take a very active role in my medical situation more than once. Once I was told that my problems with range of motion in my right arm (couldn't put hand in right rear pocket and had lots of pain trying) was simply old age. I inquired as to the rapid onset and was assured that arthritis comes and goes sometimes quite quickly. I went to a young sports doctor who prescribed 4 physical therapy sessions and home exercises. In two weeks my right arm worked better than before the problem surfaced. What caused the "frozen shoulder?" Driving T posts one handed with a 14 lb sledge. Still my regular doctor went for age and arthritis armed with my sledgehammer story.
If something doesn't seem right, maybe it isn't. I have great respect for doctors but they aren't omniscient. I partner with my doctor and I don't let myself be trumped by his doctorness unless I am truly satisfied with his opinion and then I frequently hit the net to get smarter on the topic of interest.
