How to treat hypersensitivity of nervous system?  the nerves have become Overactive & sensitive and is giving internal tremors starting from the occipital area and going down to the entire body. Whole body is shaking from inside and walking is also now affected , parkinsons is ruled out as F dopa is clear, also MRI brain is clear. Spine MRI shows disc bulge in C3-C4, C5-C6. The internal tremors aren't stopping. Body is getting hot like fire due to the shaking inside and there is tingling and burning too in the hands and feet, also nerves in the face and body keep pulling due to the hypersensitivity of the nerves. We have  tried antidepressants, nerve medicines, beta blockers, benzos, pain meds, ayurveda , homeopathy but nothing helps. Also tried many neurologist , psyciatrists, PT and OT but my sister is still struggling, how can we get the hypersensitivity of the nerves down? Can someone plz suggest. Thank u in advance.
