Hi. I am a 26 years old girl. I was having a skin related problem (Tinea cruris and corporis) for the past two years and was under heavy medication till Sept 2016. However during August-sept 2016 onwards I started having irregular menses. I had periods in August, missed it in sept and Oct, again got periods in November then missed it in December and January. Now, the problem that I have is during first week of December, while I was in sleep, my body got stiff and I tried to scream which I was unable to do as my teeth were clenched. After almost 7-10 mins, I could gain consciousness and realized that I had bitten my tongue (maybe that's coz of teeth clenching) and immediately after I vomited too. I had thought it's coz of my exam pressure but the same incident happened last week again. This time for around 5 mins. Both time I was in deep sleep.
