Bicepital tendonitis. Muscle weakness.

1 month ago I was having severe pain in my left shoulder (just one day after I woke up it started), I consulted an orthopedist, he told me it is Bicepital tendonitis and gave me a few pain killers and referred IFT treatment at a physiotherapist. I took 2 sessions of IFT and then I had to move out of city. After a week of the session the pain stopped but till now it is very difficult for me to lift any kind of weight using that hand and the shoulder gets tired by even some short movements. I consulted another physiotherapist and she gave me 2 sessions of LWD and some exercises. Do I need to continue the LWD or just exercises are enough, since there is no more pain as such, its just muscle weakness.
