One month throat problem. Type feeling.

Since one month i am facing problems in throat. Pain in swallowing part of throat feeling of something stuck in throat, in April first week i took acidity medicine after a general checkup with a doctor those medicine didn't helped. I dont have any heartburn problem but a burp feeling.  ALSO NOTICED A SMALL WHITE VERY SMALL WHITE PIMPLE TYPE ON TONSIL WALL ON ONE SIDE BUT THAT DOESN'T HURT. Since 2 days taking zerodol sp and pantocid when i take zerodol sp it makes me feel better for sometime but again i have that throat feeling of something stuck. I dont find difficulty in eating but there is always something stuck. Its been a month no doctors available for endoscopy to examine and clear checkup. I dont have any other health symptoms only problem is something stuck feeling and pain in that area dryness in mouth and in evening a sore throat type feeling.
