Hello overwhelmed. I have had many of the same symptoms you are having including joint, back,head,and abdominal pain. My left knee became inflamed so much I had to have arthroscopic surgery and it took 12 months for my knee to feel ok again. I am in debt to the tune of $60,000+ in medical, urgent care, and emergency room visits. I am almost 44 years old and I just found out I am allergic to wheat, corn, walnuts and peanuts today. No doctor could ever figure out what was wrong with me because fat people don't have food allergies. I was tested for celiac's but it came back negative. I have had two kids and now I am worried for their health. I have a friend with celiacs; so I am familiar with not being able to eat gluten. I have had so much gas and bloating my daughter asked me if i was pregnant again. Thank goodness I know lots of recipes and most times am a vegetarian. I don't think we can eat any soy products since we are allergic to peanuts. Stay away from all commercially produced (packaged) baked goods, candies, fried and then frozen foods, potato chips, corn tortilla chips. This means no more gluten free corn bread muffins. It is good thing to be checked out now. Make sure to wash off all your fruits and veggies even bananas. Now I have to get my kids tested for these allergies.
