In the past few days, I have been experiences some stomach pains, which I first attributed to my period which I just started yesterday, but these pains felt different than cramps. It felt like a jabbing pain. Then when I was on the bus coming home from work yesterday, I started to have a severe panic attack with ears ringing, going numb, blacking out slightly and cold-sweats. I still also had the pain in my stomach and also experienced diaherrea earlier that day and when I got home. Even when my stomach felt better last evening, it was still 'gurgling'. today, I do feel better but I still have a slight pain, not too much of an appetite and still slightly nautious since yesterday. I read some stuff online and thought that maybe it could be an ulcer, but if so, would that trigger the panic issue? Since I've been on Paxil for the past 6 yrs or so now, I have had very little problems with them at all. This is why I got worried when I experienced the bad one yesterday.Please help.
