hi,
thank you for providing the brief history of you.
A thorough neuromuscular assessment is advised.
i read your whole history and what i understood is you had
plantar fasciitis in the past for which you have undergone the
physical therapy.. So now you have different symptoms like
radiating pain which falls between the lower back and the foot. I will advice to first undergo a clinical neuromuscular assessment as this will help us further about the mechanism of
injury.
As you had a past history of plantar fasciitis, what mechanism could have occured as per my understanding of the biomechanis of the human body, is that, the pain in the plantar fasciitis must have changed your gait and lead to a repetitive
stress on the
lumbar spine by which the nerve must have got pinched and the symptoms are arising now. Also, taking an MRI of lumbar spine, your
soft tissue status can be determined. Post which, physical therapy will be advised and your case has to be treated in a special manner rather the conventional one. As the plantar fasciitis is the past history and the present history is the radiating pain.
In my clinical practice i have seen cases with similar issues and mechanism of the symptoms arise with initial issue leading to secondary injury. But with graded physical therapy they recover better with 99% optimum results.
