This is a good question. It is important that you make an appointment with your primary care doctor
to discuss your symptoms and have a full history and physical. Depending on what your doctor discovers during your visit, he or she may order additional testing such as blood work. There are many possible causes for your symptoms. One of the possible explanations is depression. Depression often manifests as physical symptoms, such as aches and pains, as well as a depressed mood. Other symptoms of depression include insomnia
, changes in appetite, lack of motivation, and guilt. Another possibility is a problem with your thyroid, such as hypothyroidism. This can cause fatigue, depression, weight gain, constipation and dry skin. Your doctor can check for this by a thyroid exam and a blood test. Another possibility is a rheumatological disease such as lupus, fibromyalgia, or rheumatoid arthritis. These can also be screened for with blood work. Again, it is very important to make an appointment with your primary care doctor to get a correct diagnosis and appropriate treatment. In the meantime, make sure to get at least 8 hours of sleep, drink plenty of water, eat a healthy diet, and get at least 30 minutes of exercise a day.
