I had difficulty swallowing last week and throat was paining like if there is needle inside. I went to GP after 2 days and he said that it's ulcer on my tonsils. He asked me only to gargle and take Sinarest LP in order to stop further spread. It's been more than a week now pain is very less but it does pain sometimes. I am scared if it is normal ulcer or something else. Shall I get blood tests done? Note:I had reflux acidity problem from last 1 month which is now quite under control. Also sometimes my upper left stomach hurts a little.
