My ears??????????????????????????…

ok for the past few days, my ears have been feeling weird, last week I went swimming and I got water in my ear, and it felt like that was gone after the first few days, but then the other day both my ears felt like I had water in them but I only got water in one, but it's not like that feeling where you can hear a echo when you heat just sometimes my ear crackles and I feel like theres something like water in them, and sometimes they my left one hurts a bit but not much, wat is it, could it be a ear infection or ear wax or something?
