Today the ear doctor did a procedure to drain the liquid did he removed it or its going to drain?

Likely both: Your ear doctor likely performed a myringotomy, which is a small hole in your eardrum, to drain the fluid behind the eardrum. Typically at the time of the myringotomy we drain as much as the fluid as we can, but we cannot drain all of it at that time because there is likely more fluid hidden that we cannot see. Over the next day or so, some of that fluid will continue to drain as it clears.
