It sound more like a powersteering pump issue it may be on the way out. do you do alot of full lock turns while the car is still stationary? f this is the case you put alot of stress on the pump which will shortern the life of the power steering pump.

You could try changing your power steering fluid even if it isn't due for a change to see if it will help a little. Just remember to replace the power steering fluid with genuine honda power steering fluid.
