Symptoms: I am sorry to hear about your struggle. Unfortunately, you're not alone. In that case, psychological issues should be ruled out (stress, depression, etc.). Also, strange as it is, i believe that there may be some toxic substances you are exposed to in the food you eat especially if it is full of preservatives, additives, gmos, etc. It may be worthwhile to go more organic.

? Connective tissue : Systemic symptoms of fatigue, joint aches, headache, along with chest and back pain could signal an autoimmune problem. Make sure an autoimmune loos panel is done, with possible rheumatology referral if abnormalities found. Consider sleep apnea/patent oreamen ovale as well.
