Is it normal to feel a burning sensation in the head,throat and chest  associate with anxiety for more than a day? I have been extremly stressed out lately these days due to my OCD intrusive thoughts and I noticed at time when I felt stressed I feel a burning sensation in my throat and get a scratchy feeling that goes away after a while. Yesterday  night I couldn't get any sleep due to my stress so I experience and keep getting these burning sensation that lasted the whole night and into the morning I still experienced it. I feel it in my side of my head and it feel like some hot liquid is pouring down in my inside. I am stressed out and worried that it could be a medical issue like brain fluid  leakage. Is it normal for this to happen with high stress or is it something else?
