If the exercises are causing you pain you probably do need to stop at the level that you’re at or reduce them for a little while until the pain has gone away. The squats will help both of your legs and it’s important to exercise both as equally as you can.
It does sound like your brain is trying to rewire its lost connections as you are getting some movements in your fingers and thumbs. Hopefully this will continue and improve over the coming weeks and months.
When I do 1 leg stands I bend my knee after counting 5 then stand at 10. I do that at count of 15 and 20 too as I think it will build muscle in my legs
It should definitely help build your muscle strength up.
I do them twice a day every day.
How are you doing Anne?
You’re squats are probably just getting too easy for you. Either take a week off from doing them. Muscle work does need a few days off once a month to avoid these plateaus. When you go go back to it, you will certainly feel it next day. So you’ll know the muscles are growing a little bit more.
That’s also why body builders will do upper one day and lower body the next. It allows muscle to rest and repair themselves. And between that and high protein diet That’s what gets the muscles growing. But I think you know all that anyway🙂
It does sound like good things are happening with connectivity to your arm and leg. All that hard work is finally paying off

Ok love thanks for the advice
I’m doing ok thanks.
Some good advice from Lorraine there. You can exercise too much sometimes. Resting is important too.
Problem I have Anne is that if I stop I might not start doing them again with the way I feel.
I do the same routine everyday except weekend where I watch a film on Netflix and have a couple of cans to chill
If you are having a break at the weekend then that should be ok as you are giving uiur muscles chance to recover.
It is hard to keep going if you have a break. I have found that myself at times. I just tell myself though that I won’t improve of I don’t keep motivated to try.
Thanks for the advice Anne
Hi Anne just to let you know that I have a feeling my tennis elbow is easing. Still get the odd elbow pain and my shoulder clicks but it’s ok when I’m walking
That’s good news. Hopefully the remaining issues will resolve soon.
