Weakness is a lack of physical or muscle strength. You may feel that you need to make extra effort to move your arms, legs, or other muscles. Generalized weakness means that you feel weak in most areas of your body. Another type of weakness may affect just one muscle or group of muscles.
You may feel weak and tired after you have done too much activity, such as taking an extra-long hike. This is not a serious problem. It often goes away on its own.
Feeling weak can also be caused by medical conditions like thyroid problems, depression, or a virus. Sometimes the cause can be serious. Your doctor may want to do more tests to try to find the cause of the weakness.
The doctor has checked you carefully, but problems can develop later. If you notice any problems or new symptoms, get medical treatment right away.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor
or nurse call line if you are having problems. It's also a good idea to know your test results and
keep a list of the medicines you take.
