Suggestion Of Cure For Strong Sensations In The Head Coupled With Shivering

Hi I have been experiencing some strange sensations over the back of my head & also along my right forearm. I have two ways of describing the sensations which the first one is like a very slight shiver effect which initially started about 5 days ago. It happens every couple of minutes & its travels like a wave from the back of my head near the top of the neck ( from middle to right side) & over my scalp to towards the right front. There is no pain it is very much sensation. A first I was getting a cold feeling in the area after the wave & this is why I relate it to a shiver. It lasts for about 2 seconds. The exact same thing was happening with my right arm around the elbow forearm area. The last day or two it seems to feel like the cold effect has gone & it seems more liKe a static electricity wave. More with a warm sensation than a cold one now . No headaches no pains, been under some stress due to an exam now completed. Not long finished a bottle of Zeolite & taking prebiotic capsules as well as some vitamins selenium,taurine , multi, vitamin d, garlic caps & vit e caps. Attend Numerous gym classes a week & swim. I m female & 46 yrs old . Any ideas ??
