Not sure what I could have done differently on flop, maybe check raise? Or just bet higer I guess. Turn card is ugly though and when he raises me im really not sure where I stand. Its only a $4 sng and people love to limp in with crap like TJ and JQ from EP so I felt it was entirely possible he had the higher straight. Set was another possibility too. Anyway, what to do from here? And on the river if I call

I would pot the flop. Someone is likely to have hit and will pay you off.

As played I would call and probably donk bet the river.

Flop bet might be a bit low, but if he's on a draw in a $4.40...it's unlikely he will fold to any bet.

As for the turn, I'm shutting down here. I don't mind the $200 for information, but when he raises I pull a muscle hitting the fold button.

Meh, that's probably the best line. I just hate folding to small raises.

You can't fold for 250 here. At this level, two pair or a set is possible. Yeah, you're beat sometimes, but I think you're ahead enough to make the call. You probably have to call the river bet, too.
