5 weeks is early in the process but you may well regain full movement of all your limbs. It takes work, determination and concentration. It took me about 9 months to stop veering to the left if I didn't concentrate when walking but either my brain has rewired to stop it or I concentrate automatically now, I don't know which but it works. My left arm was also affected but by concentrating on making small movements almost constantly for a period of months I have regained the full range of movement and sensitivity. It's hard work but don't let it beat you, you can do it.
