Severe Foot Pain - Is it Plantar Fasciitis?

I was recently diagnosed with plantar fasciitis in both feet. My left heal and ankle were hurting so bad I could barely walk. I had to go back to physical therapy and they just started ultrasound on that foot which really helps. I had a cortisone shot but it didn't help much. You need to stretch the back of your calf muscles that's where plantar fasciitis originates. And grab your big toes and stretch the bottom of your feet and ankle.
