Hi,
I did look into osgood schlatters but there is no visible sized bump nor is my leg tender to touch well no more than the other one anyway.
The pain is more inside of the tibia on the posterior side. It just feels like a stress pain. I did initally think stress fracture but being 2 years it would have healed by now.
I will see a physio when I can but there is always a waiting list and if I can figure out what it is then I can fix it.
Could it potentially be shin splints? I have had it before in the same leg but much closer to the ankle.
