Erin - Why would you call your neurologist because your hair is falling out? If my I called my neuro and talked to him about hair loss, he would certainly recommend I get in touch with my primary care doctor. Of course, I wouldn't call him for hair loss. I'd be calling my PCP.

Hair loss can be caused by many illness, vitamin deficiencies, trauma, hormones and even mental illnesses. I know it can be quite alarming to start losing clumps of hair. I am going through this myself; however, I know the cause of it and know that eventually it will stop once my body heals more. I do understand your concern and can emphasis.

When you had all your blood work done, did they check your thyroid? Your doctor can run another test for that as well as other blood tests such as your B12. He/she can also run tests to check to see what your hormone levels are. You are now in your 40's and hair loss, joint pain, muscle pain, fatigue, etc. call all be caused by perimenopause and hormonal fluctuations.
