Hi Aleisha,
My daughter once had something like that that seemed to go on forever. She didn't seem sick at all but just sounded like she was loosing her voice all the time. I took her to the doctor and in her case he said she had some post-nasal drainage in the back of her throat probably left over from a virus. We gave her lots of fluids and she was fine. Since its been going on for a while with your son, I think I would check with his doctor. With the crazy spring weather and all of the colds and stuff going around right now its probably something related to that, but if you have him checked you won't have to worry anymore. Good luck and I hope it gets better soon!
