The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
In anything you try, I do not think it will take one session to magically fix. If NKT is working for you, you might consider going for a while regularly to see if it will eventually reset your CNS and things will get back to normal. it is encouraging that you had a 24 hour good result. but to expect longer than that from the first session is probably too much.
