hi there, I have been experiencing pin prick and/or cramping itching and burning sensations on my skin and in my muscles all over my body for about 3 years I also get muscle twitches .it isn t super painful to touch these areas or anything and it seems to come on at random times but very often during the day and night . I m also very tired and have sore joints all the time and never feel like I m getting enough sleep . I also experience dizziness and nausea daily. I feel sort of like I m getting sick but just won t actually get sick . what could this be ?
