My lips have become inflammed in the past few weeks. I never had inflammation before. I am sure that the inflammation is caused due to drinking bad kefir.
3 weeks back I started making kefir at home and used to drink half a litre of it everyday for 2 weeks. In the beginning, the kefir was good but it got worse day by day and in the last few days,the kefir's smell was unpleasant but I thought that it was good until I found out that it was indeed bad.
I became sick twice in that period. I had cold and cough which I thought was due to some die off. After that I threw away the kefir grains and started making yogurt instead and have been eating yogurt for a week now. I have stopped eating yogurt too.
