someone please tell me the finger cramps will go away after awhile.... 
Do you mean from clicking too much?
Sounds like you may need to click with a lighter touch, or perhaps use a tablet. You can also reduce the strain on your fingers by being smarter with your tools. Line tool, shape tools, using a larger brush and erasing away instead of drawing a shape per-pixel, etc can help you get the result you want with less manual pixel placing. Save the mouse work for the polish stage.
If you're doing something that causes finger cramps, you'll keep getting them. You need to eliminate the cause.
