I think I have sweated more at night
since I had my eldest so 18 years ago. However over the last few years I always wake up with soaking wet top around my neck. It doesn't smell of BO but I think it's more like vinegar or yeast. I used to wash my hair twice a week but now it stinks on day two. Buy day three it's minging. I have started to use dry shampoo in between washes and even putting dilute mouth wash spirts on it straight after washing.
I don't think it's normal any more. I sweat a lot but it's more the weird smell.
Can you get yeast infections without a skin reaction?
I have been almost at pre diabetes levels for a while too. Had oedema really badly with no known cause for a year as well if that might be linked
