I really recommend this guy's course for all mobility issues. I have a lifelong should problem which physio's could not completely fix. I am 2 thirds the way through the should control routine and have seen amazing results. There is still 6 months worth of courses (Scap strength and should flexibility solution) to go so i am confident it will be fixed in the end.
There are courses for the entire body. There is very likely a course for any mobility issues you have.
There is an annual subscription where you get access toa ll courses and the Facebook mastermind group. It was around £250. Well worth the money and much cheaper than physio.
It does take dedication though. Stretches every day. Although not your average stretches. Some are very taxing!
