Gluten Free???

My food allergies have happened in waves.  I couldn't tolerate milk as a baby, but grew out of it (supposedly).  Then, all of a sudden, in my early twenties I started to have reactions again.  When I cut out dairy and added a lot of soy products to my diet, I  began to react to soy.  Also, my digestive issues never fully resolved.  Within the past couple of months, I've started to react to eggs....not horribly, just a little skin rash, but I'm thinking, what's going on with my body???

Recently, my dad went gluten free to help some of his health issues, and within 2 weeks, he was feeling better.  I had a revelation: maybe I have an underlying sensitivity to gluten that is causing my immune system to go haywire (I've read about this many times)...
SO, heres my question:  is it ok to just cut it out and see what happens? or should I go to the doctor and get a diagnosis? I have heard many differing opinions, so if anyone has any advice to offer, please let me know!!!!
