help, i'm at breaking point, every since i had my upper back tooth pulled i've been sick. Sympthing ranging from rapid heart beats, tightness in chest, lower neck pain, tenison head ache,congestin,acid reflux, ear feel clog .Been to the doctor lot of carido test done all were fine as was kidney, and adomen test. Only thing i can think of is the dental work, becuse i was fine until i had that done.
