I am a 19 year old female and in the past 2 weeks I have started getting a bunch of strange symptoms that don't seem to connect. Some will go away, some have stayed, and new ones continue to pop up. It started with epigastric pain and discomfort, there would be a constant feeling of pressure in that area and there would be a sharp pain when I swallowed. At this time there were no other symptoms. After a few days of this I went to the doctor, they were not sure what was wrong with me so they prescribed me with a week of heartburn medication to see if it would help. While I was taking the heartburn medication the pain and discomfort went away in that area, but I began have stomach pain, and occasional nausea after eating and at random points during the day. Over the past couple nights in addition to these symptoms I have been getting low-grade fevers at night every day. They are gone when I wake up in the morning but they are present every night. I have been going to the bathroom normally and have noted no other symptoms. I am also not pregnant. I would really like to get a better understanding of what could be wrong with me before I go to the doctors again and undergo a bunch of tests that may not be necessary. Thank you in advance to anyone who may have an answer.
