Hi, I have been sweating during the night during my sleep around the back of my neck and sometimes on the front of my neck and it lasts for few seconds and I get awakened from it , it is only confined to the back of my neck and can sweat on my forehead also.I have been very emotionally stressed out, I am in my 40's and am feeling extremely stressed out as I am undergone several IVF cycles to try to conceive for several years without success, I am constantly thinking about it, I sleep and wake up thinking abpout it.can this be due to anxiety and stress? it is happening a copule of times a week now.
