Hello doctor? Am a male aged 24 years 5 5' tall. For some time doctor i have had some problem with my stomach. When i am asleep, i feel a mild disorder, as if something is being digested slowly overnight. When i am walking i dont feel anything and when am upright. Again, when i press the left side me my belly, i burp or belch. Also when i gently punch my stomach from the back bone, i still release gas. My belly feels full when i eat and it relaxes when i go for a long call. Any help please because this is the fourth month after i have been treated for amoebiasis using tinidazole but that could only change during the period of drugs then the same feeling would come back. Help me.
