I am 20 years old and have been on Yasmin for PCOS/mood swings/irregular periods since I was about 16 or 17. This past December, I was out with friends when I suddenly had this awful, all-over terrible shaky feeling, thinking I was going to pass out, die, or vomit. I had pressure all over and my tongue felt thick in my mouth, lump in throat and had to go home immediately. I thought I was getting some kind of flu. Weird feelings kept continually happening to me every day since then and the symptoms change over time and last for different lengths. I've mostly experienced tightness/strain/pressure in my throat, lump of pressure caught there, almost numb pressure sensation under my tongue, jaw, and up into my ears, an ache/pressure in chest and sternum. I stopped taking Yasmin, switched to Aviane which made me nauseous constantly and have been off BC over a month now. I have been told it's anxiety constantly by two different doctors, gone to ER, had blood work, thyroid checked, ENT stuck scope down my throat, everything. I was given Klonopin which never seemed to do anything to me, was given meds for acid reflux which did nothing. Even after getting off BC my emotions have also gone haywire and I feel at an all-time low and this is ruining my life and my relationship with my boyfriend. I finally gave in and tried Xanax. The first two times I've taken it, I felt great for the rest of the evening and slept well. Today was the third day and I felt fine for about two or three hours and the pressure in my throat and under my jaw is back again. Does anyone think this could be anxiety or something else, or does it truly seem to be Yasmin?? I'm at my wits end and would like to go back on the pill for my emotions/periods if possible but I'm so afraid in case that caused my problems. I feel helpless and always in pain and discomfort.
