All good stuff. Really good information sites.
As a physio, I had a recent lingering bout of plantar fasciitis myself after a sudden 20 km walk in the wilderness.
Just wanted to add:
- Keep up with the icing. The frozen water bottle is just perfect.
- Keep up with plantar fascia taping, it can give your foot the needed relief time to make the shift to healing. If your tape job isn't working, try a different plantar fascia tape job.
- Address the tibial posterior. It's a muscle that supports the arch. You're high arched but you wear orthotics. Perhaps your arch "collapses" as you walk. This stresses the tibial posterior, which can cause an whole lot of pain in your arch heel area. Here's a link that may be helpful Posterior Tibial Tendonitis/Insufficiency Treatment: Trigger Point Massage The diagram doesn't show very well how closer to the ankle the muscle really hugs the tibia bone and curls round the medial maleolus into the arch of the foot. That would help you get an idea of how to release the muscle in its lower areas.
- If your tib post is affected, you'll know by the painful massage, look into strengthening it (and not straining it with bad shoes.)
- The dry needling is awesome as Simon says, and can be painful, but the kind of painful that brings relief.
Good luck. As Ezrida says, each treatment is unique to the individual. So finding a physio who will address you as an individual, rather than here's my regular plantar fasciitis treatment applied to you, is what may turn the corner.
