Hi
Welcome to the forum!
The sensation of pins and tingling in hands and feet can be due to peripheral neuropathies or peripheral vascular pathologies like deep vein thrombosis and faulty deep vein valves. Hypoparathyroidism should be looked into apart from hypothyroidism and diabetes. Neck strain, spondylotic changes in cervical vertebrae, bone disease or bad posture should be looked into. Multiple sclerosis and G B Syndrome (chances are less) are two other possibilities. Nerve infections as in Lyme’s disease too should be investigated.
However confirmed diagnosis cannot be given on net. Please discuss this with an internal medicine specialist or your PCP and get the required investigations done. Hope this helps. Take care!
