Probably all the alcohol and the junk food has resulted in gastritis
and also oesophagitis which is causing heart burn, pain and a feeling of something being stuck in the chest. The inflammed throat may be because of reflux of acid into the throat. You may take a Pan 40, syrup sucralfate
and a prokinetic like domstal
. Avoid alcohol atleast till your symptoms abate. Take a pain killer like calpol
for bodyache and take rest. All your symptoms are because of alcohol excess and there is no need to be anxious about cancer as at this stage it looks unlikely.
