Hi doctors My son swallow a hard mango candy in afternoon and he started coughing like sticking but slowly he settled down and we give him water. And the he slept well. After waking he was burping crying just in middle And meanwhile he cough like something stuck or like something want to come out . And in night few minutes ago he drink 1 glass milk and after 5 minutes he cried a lot and he vomits whole milk. I think it's is because of gas. What can I give him for gas for sudden pain or vomit
