Question: I have had twitching calves for 8 months with extreme cramping in legs feet at night. I was under enormous stress, the after things calmed down. About 2 months ago I started having unusual neurological symptoms. It statred with legs twitching fast viable the body jerks, I was hospitalized and they came up with slight low magnesium, I had a MRI of my cervical spine C5 C6 severe stenosis. bulging disks at every level my primary put me on valium and hydrocodone for the pain. The I began to get numb everywhere in my head, mostly in the morning, never sleep longer than a hour and half up with cramps or urinating, I have a buzzing of electricity at the base of my brain upper neck seems to be more present when I'm in spasms , that can last for days valium helps. somewhat I have a GFR of 35 Creatinine of 1.5 Medullary Sponge KIdney and chronic calcifications, had 3 surgerys to remove stones my nephrologist says this is not kidney related. I was reviewed in the hospital by a neurologist who specialized in ASL and Parkinson's doesn't think its related, thr MRI of my brain was inconclusive some symmetrical white matter and some other white matter but not in the pattern of MS. My Mother has MS. At this point the symptons have calmed downa day or so I have a sore throat and I am just exhausted. My neck is somewhat stiff but not as bad I do get the sere numbness in the morning and when I turn my head, also calves still twitch medicines calming that too. I was on prednisone for a week and all my symptoms disappeared except the twitching in calves if that helps

I am not on any cholesterol lowering drugs like statin's. My blood pressure. cholesterol is fine. I exercise daily. I weigh 130 at 5' 6". I went to the nueor and neuro surgeon. The surgeon said that my neck could be causing some symptoms but not all. My bloodwork comes back fine other than low GFR and Creatinine but I do have MSK ? I have been drinking Quinine it doesn't help?

I was under the impression that vasculitis has a rash type component, I have no rash. Is it possible to havr Vasculitis without a rah and what type.

I was hospitalized with a severe headache they did a CT scan which showed nothing. They also tested me for vasculitis that came back negative the doctor asked me if there was any medicine that made me feel better and steroids are the only thing that helps, my neck is severely spasming. after starting the steroids itwas the only relief I got. I have been tested for all neurological problems,the neurosurgeon did not believe these problems are from my neck. I am trying to figure out the direction I should go in now. Thank you for your help!
