Multiple myeloma (MM) symptoms usually do not appear until it is in later stages. It develops slowly over many years. In many people, it is found during routine blood or urine testing. In those that have them, symptoms depend on where the tumor is and what types of blood cells are affected.
If you have these, do not think it is because of MM. Other, less serious conditions can cause these problems. But, you should still talk to your doctor about them. Finding and treating the cause early will improve the chances for a cure.
Common Symptoms
The most common problems caused by MM are:
- Bone pain—Mainly in the back, hips, ribs, or skull. Bone tissue is broken down faster than it is built up. This causes the bones to weaken. Bone pain can also be caused by growing tumors.
- Broken bones—Weak bones increase the risk of breaks. Even small breaks will cause pain.
- Unintended weight loss
Other Symptoms
MM can cause a wide range of other, less common symptoms such as:
- Burning or tingling pain, or numbness or muscle weakness caused by peripheral neuropathy or carpal tunnel syndrome
- Feeling weak or tired
- Fever or frequent infections that last longer than normal
