Yes, do the PT for both your left ankle and your right hip. Be sure to warm up affected areas before PT and ice them afterward. If you cannot use the bicycle to warm up, you need to find an alternative. If you have access to a swimming pool, you might ask your PT to design a program you can do in the water, where you can go through range-of-motion exercises without weight bearing. Consider it a plus if your swimming pool also has a hot tub where you can sit for a short time to warm up before using the therapy pool. But don’t use the hot tub after the pool; use ice then to prevent swelling.
