[My hand gets swollen. Sometimes, I am stiff or get joint pain (hands mostly). I can’t lift my body easy or manipulate objects, and have poor coordination. I also have had frequent urination, bowel changes, chest tightness (EKG, chest X-ray ok) coming and going, issues with my voice (hoarse) intermittently and a constant metallic taste (no antibiotics).]

Are most of your symptoms in your hands /arms, very little in your legs?
If the uterus was pressing on a nerve I would expect the legs or lower extremities would possibly be affected..not the arms/hands..

What kind of job or activities do you do? - desk/computer/ repetitive/weightlifting?
Have you had any MRI of the c spine since there is arm/hand sx?
Do you have any neck/upper back pain or tightness?
any whiplash type accident or falls in the past?

Have you considered expert chiropractic, acupuncture, naturopathy?
