### input:
Yes I have degenerative arthritis in the lower lumber and stenosis in the lower back. One day I twisted in bed and heard something pop like when you crack a knuckle. After that my back felt better and I had no pressure, which was constant before. Then I started to get this pulsing vibration from the bottom of my right foot up my leg , back chest to my right shoulder. This was in Jan. of last yr., it gets louder when I m tired or startled. Feb. 22 I went to my Doctor, my blood pressure was up, and I was stressed and wired, could not sleep due to this vibrating.. Couldn t take meds. because it gave me side effects. Told doctor let me see if I can calm my self. Finally did. He thought this vibration was my blood pressure. When my blood pressure is at 125/72, I m still vibrating. I had an MRI in Sept. before this happened in Jan. Could it be spinal fluid. It drives you crazy. Sometimes it goes away. If I get startled it rumbles like a train. I hear alot of people complain about this, but no one knows what it is.

### output:

Hi, I value your concern regarding the symptoms. I have gone through your symptoms, and in my opinion your problem is over concern, do not be carried away with your symptoms, spinal fluid will not cause such symptoms, get yourself screened with MRI of back if you have doubts. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health. Special note-Any medication prescribed needs to be taken after consultation with your personal doctor only.
