hello and welcome to HCM,
It is imperative that you see an ENT as soon as possible because of these points:
1. A discharge from the nose without
cold can happen due to many causes but the most worrisome is a condition called the CSF
rhinorrhoea. If this is what is causing your leak then it has to be taken care of immediately as it may lead to infection of the brain.
2. You need to undergo
endoscopy to try and delineate the cause of the leak
3. A routine CT may not be very helpful in this condition, you need to go for a CT called the contrast CT for proper diagnosis in this condition
4. Collect a sample of the fluid and send it for CSF analysis
5. Your diet change may also have something to do with the leak indirectly so give full information of the type of change to your doctor
do not strain and do not blow your nose
take care and get well soon
