Vibration inside/under heel lasting 2 seconds. Stop 4-5. Repeat. No spur (per x-ray). Mild swelling posteriorly mid calf to achilles. Hair loss on leg?

Vibration. more than likely the vibration is nerve pain. Some cases of plantar fasciitis involve the infracalcaneal nerve branch under the heel- it gets entrapped when there is a lot of inflammation. Antiinflammatories help, or ice. The mid calf pain could be posterior tibial tendinitis - the tendon that holds up your arch. This tendon and plantar fasciitis are related. Try an arch support.
