But statins themselves can cause problems. Side effects can vary between different statins, says the NHS, but common side effects include headache, dizziness, feeling sick, digestive system problems, such as constipation and diarrhoea, sleep problems and low blood platelet count.
Another common side effect is muscle pain. According to Mayo Clinic mild muscle pain is a relatively common side effect of statins.
But it adds: “Some people who take statin medications to lower their cholesterol may have severe muscle pain.
“This intense pain may be a symptom of rhabdomyolysis (rab-doe-my-OL-ih-sis), a rare condition that causes muscle cells to break down.”
