I am 19 years old. I have been feeling sick for exactly 2 years now. And it keeps gettitng worse. I have been to the doctor a lot of times and everytime it is something different. My stomach gets like really irritated that i want to cry. I am nauseas a lot of times. Sometimes I am dizzy, i get a lot of headaches, yesterday I started to get a brownish discharge on my pantiliner. My stomach swells a lot and it hurts. Yesterday evening my heart started to beat heavy fast and I got a big headache. I get cramps in my lower abdomen. I struggle with heartburn. Sometimes I get like a fever and i get fatigue. Should I see a doctor?
