Normal blood work. bone pain, joint pain, migraines, problems with almost passing out, bad balance and coordination. any ideas? the drs are stumped.

Ears checked?: Although the joint/bone pain is not typically associated with an inner ear problem, your other symptoms can be. A neurootologist would be the doc to see to have your ears/hearing/inner ear pressure checked. The other issue is that an endocrine abnormality or pituitary problem may be the underlying condition causing all your symptoms. I would likely discuss referral to endocrine & ear doc w/PCP.
