I have a problem of smell coming from my nose . People come near me rub their nose.
I cannot understand anything. But I can understand from their expression. Its about 2 years am facing it.its really horrible. I am getting totally isolated even with my family.someone help to get a solution.

Have you seen a doctor about this?

Do you bath regularly? Do you clean your nose/face regularly?

There are a few medication conditions that could cause a person to smell bad, but I can't recall what they are. It is best to see a doctor, they'll probably be able to narrow it down.

Do you smell this odor, or is there a possibility you are imagining that these people are doing that? It would have to actually be horribly strong for anyone simply walking past you to even notice from an average distance.

I walk past homeless people every day that live on the street and I don't even notice it... and I have a very good sense of smell.

Agreed, we first need to know if you have proof of your nose emitting a smell.
If you do, we might be able to help on the medical front.
Being isolated from your own family, however, suggests that the subject has never even been discussed, and you are isolating yourself for reasons having to do with imagined fears.
We might be able to help with that too.

If there really is an odor, Probblems with your teeth can cause odors that to you might be incredibly strong ( and if it gets really bad, to others as well)... look where your nose is and how its conneted to your sinuses and throat and you see why.

I am afraid to ask someone about it. One time asked my brother about it . He told nothing is there . But everyone comes near me regularly take a strong sniff inside or rub their nose. I am brushing regularly ,taking bath everyday.one day there was an incident that one man sitting near me in an air conditioned room walked away from me in an anger.But 2 years before am leaving a normal life . But if someone comes near me am afraid to be close and something happening psychologically and I will not stay with them longer.
