If, and ONLY if, your doctor has told you to take the prednisone as needed, I would surely be tempted to try it. Prednisone is fairly quick, no 'build up in your system" needed.
However, if you don't regularly take any over the counter anti-inflammatories, it might be better to start with ibuprofen at the maximum dosage. That may take care of the issue without having to rely on a possible mis-use of prednisone.
Have fun & don't get hurt!
