JJ multiway flops top set, plays badly?

[sethypooh21]

~40 left in a 10/180, I'm about average (12kish), most of the table is pretty healthy - blinds 150/300/25

I'm on the button with red JJ, 3 limps(!) tightish MP with about 14k opens to 800. I just call, 2 limpers call, pot = ~3000.

Flop Js7c2h,

Check to MP who bets 2k, I call, both ep limpers fold.

Turn 3c.

MP checks, I check

River Tc.

MP bets 3600, I call

Comments welcome on all streets.
