I am not clear on the information you have given. What i have understood is that you have pain on the right side of the abdomen, have heartburn
, feeling full easily and fatigue
Spleen is present on the upper left side of your abdomen and the presence of cyst can be confimed only by an investigation like an ultrasound
I think probably you are suffering from Acid Peptic Disease(APD) so please take cap.Omeprazole
40mg once daily for 15days. Also take B-Complex and iron tables because you have fatigue. Get well soon. Regards, Dr.Ismail.
