I am currently dealing with allergies with thier symptoms of pressure headaches, fatigue, sneezing, itchy throat, stuffy nose, muscle aches and pains, and chills. I ve had allergies all my life so I know these usual symptoms, however I have been needing to go to the bathroom and haveing diarrhea, like about once every two hours. I have never had this, can you please tell me what this might be?
