I was diagnosed with a sinus infection/ bronchitis a few weeks ago. Actual illness was not clear. Now I have severe muscle aches, twitches, rib and stomach discomfort, leg cramps, breathing problems, fatigue, acid reflux, tingling in feet, sinus headache, stuffy nose, sore throat, foggy mind, soreness near clavicle. Numerous ER tests and chest xrays look fine. What is going on? Is there a connection to food allergies?
