I replaced the faucet and the shut off valve under the sink both were cloged with lime deposits but still the hot side does not work. All other sinks and showers work fine. I really don't want to break into the wall and replace pipes. Is there any sort of snake or pressure blaster that I could use?

Are you certain that the line is blocked and not just the stop valve?

Hot water copper pipes calcify faster than cold. If you found deposits clogging the part under the sink, it's probably time to replace all of it. No, you can't blast it. You can look into Pex plastic piping (rated for hot) which at 1/2" d is pretty flexible and you might not have to take out much wallboard.
