[|Human|] After taking pravastatin 40mg for high cholestrol and bystolic 5 mg for high blood pressure for almost 2 years i am having leg cramps and feels like needles pricking my fingers and sometime all over my body, When i am exrercising and doing some stretches i get lots of leg cramps that is very painful. Since i have lost weight and my cholestrol is 149 and my trigs is 79, also my BP is now 106-79, I would definitely like to stop taking all these tablets. Please let me know what I should do. My weight was 167 its now 132.4. I also contracted a cough that cannot be stopped even if i take cough syrup, it is going on for months now,
[|AI|]  Hello understand your concernPravastatin can cause side effects in muscles in form of necrotizing myopathy. Which manifest in form of muscle weakness, myalgic and high CPK. Needle pricking sensation is not feature of narcotizing myopathy. Instead, it may suggest involvement of nerves-some neuropathy. Cramps in muscles are common in some electrolyte disturbances of Potassium and Calcium.  I advise you to get serum CPK, S. Calcium, S. Potassium and Nerve conduction studies of all four limbs done.
