I am a 32 year old male. I have been having chest pains for 6 months now. These chest pains are intermittent coupled with upper back pains. Also, I have been having these bouts of headaches and light headedness. I have been to a GI and performed an endoscopy and diagnosed me with insignificant hiatial hernia, mild inflammation of the esophagus and mild gastritis. I am on Nexium (40 mg twice a day). But no avail!!! I am still having these chest pains and headache bouts. Every mornig I wake up and have lot of mucous in my nose. I am beginning to get anxious. I think I have something else but the doctor thinks otherwise. My heart, urine and bloodwork checked out fine. I am at loss here and have no idea what going on. My throat too hurts sometimes. This is causing me too much stress and strain in life. Please help!!!!
