Hav a few bruises in d body while getting off packed train yesterday and now have a little body pain in the morning. should i take any medicines?

Not necessary: It sounds like you got bumped and jostled around a bit while disembarking. If the bruises are small, not to worry. It sounds like your pain is minimal so no need for medication. You could consider taking a warm bath with Epsom salts for comfort. If your bruises enlarge or your pain gets worse I suggest seeking a medical consultation for further evaluation.
