I'm a 17 year old female. I have many stomach issues and we cant figure out what they are so I am getting a food allergy test, Since then, Ive developed a sore throat with red bumps in the back of my mouth, and odd stabbing pains in my knee which has caused my foot to feel tingly. I am coughing and when I breathe deep i have stabbing pains in my back. I also am experiencing a burning feeling in my vaginal area. I'm nots sexually active. I have anxiety though. SO Confused. Leukemia, Pulmonary embolism? Ugh.
