That is a very broad question with many potential underlying causes.  Have you seen a doctor regarding these symptoms?

If not, schedule yourself for a comprehensive check-up and get comprehensive blood work done and get the following blood work done:

- CBC plus Differentials

- Full Thyroid Panel (TSH, Free T3, Free T4, T3 Uptake, TPO and Thyroid Globulin Antibodies

- Immune Panel 

- Vitamin D (25 OHD)

This will be a good start and should give some insight to your symptoms.  If your doctor does not discover what is causing your symptoms, please contact me and I can do a functional interpretation of your blood work and help you get to the bottom of this. 

Be well,
