Well, thankfully the diagnoses isn't tendinitis. But it explains why I feel pains in all my limb joints (elbows & knees), not always isolated to one area.
This is a exert from my log.
Went to see Dr Chis Bradshaw who is known for his work for football clubs such as Geelong and Collingwood.
After some testing he diagnosed me with the following:
Chronic exertional compartment syndrome is an exercise-induced muscle and nerve condition that causes pain, swelling and sometimes even disability in affected muscles of your legs or arms. The cause is excessive pressure within an isolated segment of muscle (a muscle compartment) causes chronic exertional compartment syndrome. Exercise increases the blood supply to working muscles, making them expand. If the connective tissue (fascia) that holds the muscle fibers together in a compartment doesn't also expand, pressure builds up in the compartment. Over time, the pressure cuts off some of the muscle's blood supply, leading to chronic exertional compartment syndrome. (mayoclinic.org)
For me the solution is simple. Restore the elasticity of the fascia, via lots of warm ups & massages.
Use supportive shoes all the time. I was referred to the running company in Geelong who put me on a treadmill and recorded my walking pattern.
We then went through 10 pairs of shoes until my walking pattern was fixed. So it's all up. I can train as normal provided I do lots of recovery work.
