could do with losing some but this has happened for a long time even when i was a lot younger and very thin! My cheeks are always rosy .....getting fed up of it.
I can really empathize with you as I'm exactly the same- everyone else is freezing and I'm sweating like hell.
I've got type 1 diabetes which has affected my autonomic functions, thus causing my body thermostat to go haywire.
I need to change my clothes sometimes 4 times a day, which is a real nuisence. I'm also not overweight.
I would recommend you go and see your doctor and see what he/she has to say.
