My weight seems to hover around 73 - 74 kg

I have lost about 10kg and now it seems to stay around 73-74kg and not going down further. By the way, I am having some pain in my right arm due to lifting my colleague's heavy backpack in the car using the right side as a passenger in the front seat. I have pain sleeping on the right side of the bed but too busy to see a doctor on this and go for physiotherapy. So I do light exercises at home with my right arm, so that I won't have frozen shoulder. The last time it was on the left side of my arm and it had healed with insurance payout for hospital fees.
