is a common complaint. Diffuse muscle pain is medically known as myalgias and can have multiple causes. I would recommend that you have this evaluated by your primary care doctor
. This should be evaluated because there are some severe causes of pain that are a sign of serious disease.
Firstly, it is important to see if this is coming from the muscle or another location. Your primary care doctor can investigate this by testing your blood. Creatinine Phosphokinase (or CPK) and aldolase are two proteins found in normal muscle. If muscles are being injured they will be released into the blood and therefore a simple blood test can determine if your muscles are the problem.
If it is your muscles that are causing the pain, there can be a couple causes. The most common is medication, with cholesterol medications being the biggest culprit. There are other autoimmune disease where the body attacks the muscles accidentally -- known as polymyositis. Another disease known as dermatomyositis occurs with skin changes as well and can be a sign of underlying cancer.
These symptoms can be mimicked by nerve problems. Low electrolytes (potassium or magnesium) or other nerve injuries can cause similar problems.
Talk to your doctor. This should be evaluated.
