Gluten Allergy. A gluten free diet.

I am having an bunch of issues with my body. I believe I have a gluten allergy and just needed to talk to the doctor personally. Every time I eat gluten I have problems with my stomach that includes pain my lower abdomen, the pain usually then pairs with diarrhea that is very water. I get full very fast when I eat gluten and sometimes it feel like it's stuck in my throat. Also whenever I use any non organic shampoos, my hair will fall out. My body wash will make my skin feel tight and itchy. I have suffered from on and off migraines not sure if it is from the gluten or not. Yesterday after having gluten I felt like I wasn't in control of my body and was very out of it. I don't have insurance, but I need to talk to someone about this because if I do have this allergy very severely, I need to start thinking about not living on campus to then satisfy a gluten free diet.
