I would suggest talking to your doctor about increasing the prednisone. 2 mg is quite a low dose. I've had PMR about the same length of time as you and the lowest I got was 6 mg. I'm on 10 mg now and doing well but soon to see the doctor and probably start the taper again. Like you I was very active, able to hike and bike uphill, do my yard work and home maintenance. I can do those things now, just not as much, as far or as fast. When I was on lower doses there was pain, but it was fatigue and overall poor function and quality of life that caused me to call the doctor and get back on a higher dose.
