Need Physiotherapy on my Right Arm

Tomorrow is my appointment for a physiotheraphy on my right arm due to lifting heaby back pack of my spouse from reaching behind the car, whenever we travel to e KL and it was rather frequent. I am going to claim from insurance and went for x-ray already. No surgery is required but need to go for many rounds of physiotherapy. In fact, I feel more pain than before attending the bad treatment. And the first treatment cost RM 90 for 45 minutes which was a waste of time. It will take months for the tendinitis to heal and this will incur more cost, where the most the insurance can pay for me is RM 3k!
