It would show you were getting treatment.

It wouldn't show that you were getting doctor recommended treatment and it wouldn't give you documentation from a physician explaining WHY you are still disabled.

Having ONLY additional documentation from a PT could potentially be 'bad' for your review. A PT's documention has to be specific about meeting treatment goals. It would include info like you could lift x amount of weight, y times....and had a certain ROM when you started and, hopefully, an improved ROM at the completion of therapy. Even though having some (slight) functional improvement doesn't prove that you are not still totally disabled, I would be concerned about submitting documention showing any improvement if I didn't also have documention from a specialist physician explaining how I still was disabled.

Please don't take that as advice NOT to see a PT. If ANY improvement minimizes your pain A BIT or helps your functioning, that IS a plus and you should do it.....just don't be suprised that the SSA wants to check that if you are improving, you are also still disabled. It's reasonable for the SSA to ask that.
