I am 26 year old female and unmarried if it is anything to do with my health. I have history of pcos and sinus. For last some time I experience weakness frequently. For a week or two, I am having problem in sleeping, either I am not able to sleep or getup frequently in between. I am easily worried and stressed in small things. sometimes my eyes feels as if it's nerves so tight that I am not able to close them and I don't sleep for 24 hours and more. I experience throbbing in my head and neck and fast heartbeat. I have feeling of hazziness and not able to concentrate in most daily works. For two days I am getting frequent goosebumps, shivering hands, pain in my lower leg, tingling sound from neck, it feels like my body is moving, my back near neck pains. Last night I had low bp of 92/66 n pulse rate of 94. I am worried if it is something related to nerves or spine that would be harmful or is it just stress and anxiety.
