I have a pain in my chest/lower esophagus. It hurts when I breath, drink any kind of liquid, and eat. I play softball, and recently had a root canal and have been taking antibiotics. Every time I take the antibiotics it hurts my throat and puts a stinging in my chest. I get dizzy often, and feel drained of energy some days even when I ve had a full nights rest. Sometimes my chest will just start throbbing, and have sharp pains for no apparent reason.
