So the other day I was in a hand ($10 cash game) which cost me a large amound of chips. I was holding A 10, and the flop comes A Q 7. I bet out a moderate amount at him, he calls. Another Q comes on the turn, and this card scared me a little so I checked to him. He puts in a small bet and figured it was worth it to see it to the end. Last card is a rag 5, I put in a small bet and he comes over the top of me and goes all in. Now I must have been sitting there for a good 3 or 4 minutes trying to figure out what I would do. Any queen and an AK AJ could have had me, which is what I feared most. I mucked my hand and he showed me the bluff, K 2. Keep in mind we were both pretty bit stacks at the table and I would have been crippled if I had called.

Would you have played the hand differently?

Luckily however I picked up a tell during that all-in moment, he got a little antsy

Check-call the river.
I don't think he can call your river bet with much you beat and if you feel he may be bluffing let him have another pop on the river.
