Undiagnosed severe foot pain for months – plantar fasciitis, tarsal tunnel, or something else?
Hi everyone,
I'm posting because I'm getting increasingly frustrated and honestly quite desperate trying to figure out what is causing my foot pain. I'm hoping someone here may have experienced something similar or might recognize the pattern.
About 14 months ago I developed a hip problem, which was a major issue for a long time but has gradually improved. Some time later, I started developing pain in my foot/ankle.
Initially, the pain was mainly around the ankle, so I had an MRI because we suspected an ankle joint problem. The MRI did not show an explanation, and I also had a diagnostic cortisone injection into the upper ankle joint, which did not improve the pain.
Since then, the pain has progressively worsened and changed somewhat. At the moment, it is mainly:
- underneath/behind the medial ankle (inside ankle bone)
- along the inside of the foot
- throughout parts of the sole, especially the middle of the sole
The biggest problem is how severely it is affecting my life. I can essentially no longer walk or run normally because of the pain. I used to be active and now I feel like I can't do the things I normally enjoy anymore. Even activities that don't seem like they should put much stress on the foot can trigger pain. For example, I sometimes get pain after swimming and also after cycling.
I'm honestly quite desperate at this point, because I feel extremely limited by this and I'm also very scared about how this will develop.
I've had quite a lot of investigations already, but so far there hasn't been a clear explanation.
One potentially interesting finding is that nerve conduction testing showed that the tibial nerve/Tarsal tunnel on the right side conducts more slowly and/or has a lower amplitude compared with the other side. However, I'm not sure how significant this is because I don't really have classic neuropathic symptoms. I don't have much burning, tingling or numbness. Occasionally there is some burning sensation in the sole, but most of the time the pain feels more like a deep pulling/aching pain, particularly around the medial ankle.
So I'm wondering:
Could this still be plantar fasciitis even though the pain is also quite prominent underneath the medial ankle and in the middle of the sole?
And one thing I'm also struggling with psychologically: at this point, could the pain have simply become chronic/centralized even if the original physical problem has resolved? I've recently started reading The Way Out by Alan Gordon because I'm wondering whether a chronic pain mechanism could now be contributing.
I really appreciate any help or input you can give, and I'm very grateful to hear about your experiences.
Thanks!
