There IS a form. It's called a residual functional capacity form. Google: "residual functional capacity form" and you can find several examples of them. The best ones are pretty detailed and sometimes tailored to your physical problem.

If you have mental health issues too, you can get a mental health residual functional capacity form filled out.

It's important to note that Social Security won't care if your doc thinks that you're disabled. That decision, being disabled, is Social Security's decision. What it will care about is whether or not your problems have an impact on your ability to work. So the best thing that you can do is get records from EVERY doc that you've seen for problems.

Tell SSA about all the docs you've seen. They are supposed to get the records but don't always do that. You should follow up, pretty closely, to see if it does get the records. And if it doesn't, then you need to make a stink to make it GET the records. Or get them yourself and submit them (keeping copies of them for your own records).

Don't be discouraged if you're denied initially. If you have a real problem, and it sounds like you do, then keep at it. Get an attorney if you need to if you're denied--someone who does a lot of Social Security disability work. Look at NOSSCR for an attorney in your area if it comes down to that.

best of luck!
