Saturday night around 730, my boyfriend and I had sex. When I'm on top, and he thrusts hard while I'm sitting straight up, it hurts and goes really deep, so I usually lay myself all the way down when he does that. But that night I sat straight up when he thrusted hard. About 8 o'clock, I started having excruciating pain in my vagina, and on the outer parts of it, also, the pain was usually where I have my cramps, and just all around my stomach. I've never felt that much pain before, I immediately laid down on the bed, but that hurt too. So I stood up, to go get some Advil or Tylenol, and I couldn't walk, i have a lot of pressure everywhere from my stomach to my vagina, so I had my boyfriend go get me some Tylenol. When he came back to the room, I had started having what we believe was an anxiety attack seizure. I usually could get the shaking to stop by falling asleep, but the pain was keeping me awake. So I just had to calm myself down for a good hour until it stopped. As of now, I still have a tightness in my stomach, but the pain in and around my vagina is gone. Last night I was awake for a good couple hours with nauseousness, back aches, and a headache. Today, I talked to my mom about the possibility of appendicitis. My father had it, and he said he got really sick with his. I might be going to the doctors soon, but what do you think?
