Hello Overit,
Sounds to me as if you are heading in the correct direction despite the frustration. I also do deep tissue work as despite the discomfort results are generally faster. Progress at the previously mentioned 10 - 15 % rate and all shoukld be well. The idea of making an appointment with the specialist just in case is a good move. You probably won't need it.
All the best,
