My nose runs profusely whenever I eat hot food

This isn't really about Autism but I'm posting it in the "Health and wellbeing" section as it's related to that.

A few years ago after I had an argument with a man he punched my nose and ever since then it's run when I eat anything warm or hot.

I get through a lot of tissues and toilet paper and it's uncomfortable.

I've visited a few GPs about it but they only give me Nometasone spray which doesn't stop it. Does anyone know what other help I can get?
