Hi, I am a 24 year old female and over the last week or so I have experienced some symptoms in my digestive tract that aren't normal for me. My symptoms are as follows: bloating, constipation, stomach sensitivity/ upset, vomiting (only once and it was recently), constant dull headaches, and some back pain. I know I am not pregnant and am a frequent migraine sufferer, and usually take Excedrin for my migraines, I am also constantly cold in my fingers and toes.
