Dr. Reed, thank you for the response. After attending physical therapy and PT having a different diagnosis than my GP, I decided to just spring for an MRI to be sure. Turns out both of them were wrong. I have trochanteric bursitis, which it seems to be a better outcome than gluteal tendinopathy. Similar symptoms and it seems like similar recovery/rehabilitation methods however.
The one issue that was revealed in my PT session, that could very well be a major contributing factor to his (in addition to the load) is that my left leg is significantly weaker than my right. I have a quite a strength imbalance there that I was unaware of. I am looking into the Evoke consultation as we speak as I would prefer to sort this out with someone very familiar with these issues.
