Are these effects from ocean water being in my ears?

2 1/2 weeks ago I was at the beach and I got a LOT of water in my ears that I couldn’t get out. I don’t know if it drained in my sleep or not, and ever since then my ears have felt very plugged to the point where people have commented on how I can’t hear them sometimes. I suffer from migraines and a trigger for them is congestion in my head, and I have been getting them a lot more than normal ever since getting water in my ears, and now every time I blow my nose the pressure in my head from doing so really hurts in my sinuses. Does this sound like I’m congested because the ocean water never came out and I need to get my ears drained or am I overthinking this?
