I have a burnt like sensation all over my mouth including my tongue. It feels numb, metallic taste like feeling.. would you know what this means?.. also it's not hot coffee.. 😊 cz I didn't burn myself.. today morning my throat felt all clogged up.. not sure what that is either.. Also note that I've been working night shifts for the past two months.. it has disturbed by sleeping schedule, I don't feel like eating much.. also very irregular bowel movements.. I have a heavy feeling in my head all the time.. also getting some rashes over my body, probably fungal.. don't know if that's related but overall a lot of discomfort.. Please help me..
