My 23 month old baby boy is pressing his umbilicus with a finger since 2 days sometimes( around 5 time in a day)..he's also telling about some pain by pointing near umbilicus (mostly left side of abdomen near umbilicus..and not on the umbilicus)..my mother in law told he also complained of similar thing around 1 week ago..he's not having any bulging in umbilicus..nor constipation or vomiting or fever..what should I do.. he's eating food normally only..about one month back he was having constipation but now it is corrected..we gave albendazole about 3-4 months back
