I am sorry to hear about your father’s medical problems. Recovery from stroke depends on how soon the blood vessel could be opened by thrombolysis and if at all it could be opened. The area and severity of infarct, the severity of underlying condition and general condition of the patient also govern recovery process. In your father’s case things appear to be serious. So, it would be best to be in touch with his doctors and take the day as it comes.
The medical advice given should not be considered a substitute for medical care provided by a doctor who can examine you. The advice may not be completely correct for you as the doctor cannot examine you and does not know your complete medical history. Hence this reply to your post should only be considered as a guiding line and you must consult your doctor at the earliest for your medical problem.
