First of all, Be relaxed .
Things are improving for you, so do not lose Hope.
You are recovering from Stroke symptoms that is a good thing ,With continuous progressive Physical therapy it can be improved and a patient can regain the full range of motion and muscle strength.(Considering patients age and other illnesses)
It can be achieved with your full faith on the therapy.
Hyberbaric oxygen therapy is beneficial,and is contraindicated in few cases ,e.g.Upper respiratory tract diseases,pneumothorax, fever ....
My brother also had a stroke and was paralyzed on his left side. He has had acupuncture and found it helpful. He was becoming discouraged and decided to try a different PT, which was a blessing. The PT recommended botox injections and his range of motion is definitely improving. It may be something to ask your Dr. about. Good luck!!!
