Hi Dan,
I think these things just take years longer than any of us have the patience for. I think it is important that you carry on with the OT exercises.
Less than a year post op is still very early, I promise!
There’s a documentary that I watched on BBC 2 several years ago which followed the recovery from stroke for a chap called Richard Gray. One of the key things I remember from that was the neuro rehab doctor said that his approach was always to do rehab exercises 7 days a week, not 5 days a week.
There are definitely others here who have had a bleed who have worked through to get good recovery. I hope some of them will see your post and be motivated to share their experience.
Very best wishes,
Richard
