Hi Sorry To Bother You! My Name Is Charlotte I

Hi sorry to bother you! My name is Charlotte I am a 19 year old reasonably healthy teenager. Recently I have been getting terribly bad pins and needles in my legs/ arms and fingers, sometimes accompanied but shooting pains which can travel up to my neck and jaw causing them to be tight. I do mainly get this when trying to sleep but during the day I tend to get very dizzy and tired for no reason. I eat healthily and exercise regularly so I'm kind of stumped! Other symptoms include headaches, a tight feeling within my head and chest, fever, blurry vision and lack of concentration. I recently had some blood test which showed up perfectly fine so the doctor felt I just needed rest but it doesn't seem to be working... Please if you have any idea as to what this could be I would appreciative it greatly as it really is getting me down at the moment as I have been suffering with this for many weeks.
