Could be reflux and colic... try not to put LO down(lay down) straight after feeding and burp LO after feeding too.
PD will check and advise on colic and reflux accordingly. TCM massage also helps
Unfortunately I am not sure about Chinese medical hall in Nigeria but I have found an article/news about Chinese medical treatment/hall in Nigeria, hope the info helps :)
