5.Medication Side Effects
Some cholesterol-lowering drugs (like statins) come with muscle pain and damage as a side effect. They cause sore, tired, or weak muscles for about 10% to 20% of people who take them. It’s rare, but statins can cause rhabdomyolysis, a rare condition that leads to muscle soreness, weakness, and swelling because of muscle tissue breakdown.
6.Anemia
Though anemia (a low red blood cell count) doesn’t typically cause pain, the lack of oxygen to your tissues does make you feel weak and tired. It’s often a sign you need more iron in your blood. You may also feel cold, short of breath, dizzy, or have an irregular heartbeat and pale skin.
