Started having some kind of chest pain about 16 years ago as a teenager. i was treated,even took ECG at a point but nothing was found and the chest pain has been off and on since then.About six month ago,i woke up in the morning feeling like something was stuck in my throat and a crawling sensation in the head that preceeded the throat feeling.went to see the doctor who placed me on antibiotics and De -worming tablets but the feeling was still there,even after using the drugs and disappeared on his own after about 5 weeks while the head crawling sensation was still there and i was on amytriptilline  for that.The throat feeling came back after another 4 weeks,lasted for  another 3-4 weeks and disappeared,its been like that for about 4 times now but this time its taken a different dimension, the throat is now giving me an up and down movement/crawling sensation,slight chest pain as i feel the sensation.the sensation get worse when i lie on my back or hot water bottle is applied on my chest and i can feel my stomach ticking at intervals.i have taken CT Scan of the chest but nothing significant was found.please,what could be wrong with me because am worried
