<s>[INST] hi from the last few months whenever I bend through my waist I will feel like water runs out of my nose suddenly and its salty water as by mistake it went to my mouth once so thats why I know its salty. should I be concerned about it and I am also suffering from gallstones and I have to take very strong pain killers for pain relief. just wanted to know if this could be linked. thanks [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. You are dealing with a condition known as CSF rhinorrhea, the salty liquid that coming from your nose may be CSF (Cerebro spinal fluid) lining your brain. It might be due to some fractures or defect in your facial bones. Consult an ENT specialist and get evaluated. You might require a CT scan for detailed evaluation. The gall stones and pain killers doesn't have any relation with this. Hope I have answered your query. Let me know if I can assist you further. </s>
