So for 4 and a half years I've suffered with unexplained symptoms. They started when my 4th daughter turned 4 months old. She's 4 and a half now. The main symptom bothering me is excessive sweating when I do minor activity and my body feel like im burning under my skin on my face and my chest and arms. My chest will sometimes will go red as well. I've had blood tests galore but apparently normal apart from vitamin D which was low 2 years ago that I had treatment for but still have these symptoms.
