I am feeling burning sensation all over my body. When the temperature outside increases my burning sensation also increases. I also feel giddy every time I sat and get up.. What can I do?? I had earlier consulted my doctor. He told me that its because of the weakness. I dont think so coz my blood level is normal. I am so worried what is happening to me. I also feel stiffness below my chest or chest you can say and it becomes difficult for me to drive two wheeler. I am so worried. I am unable to do even my day to day task. Sometimes I feel that my heart stops and suddenly it starts racing. If anyone can help me out I will be obliged to them. Thanks and Regards.
