It's been 2 months since my armpit smell has changed from normal armpit odour to a very foul 'salty' like odour. I don't know if it's my odour or something in my nose because from around that same time onions and garlics also don't smell the same to me. They smell very different to me now and I can't stand the smell like it's gone rotten. (I used to like the smell of onions/garlic but now due to changed smell i don't). Water smells different to me, soap smells different to me, food doesn't tastes the same, almost everything smells like it has been perfumed, very artificial. My breath also feels like this onion garlic type even if I haven't eaten any. 2 months ago i caught normal common cold and lost my smell and taste for a few weeks(I did not have covid but yes i didn't get tested also). After recovering from that all this mess started. So two things have happened, one the smell of armpit has changed and second changed smells of onion garlic. SAME THING HAS HAPPENED TO MY SISTER ASLO.
