Salam
I recently fell from a ladder and injured my ankle. During normal prayer I found that I could not sit on my ankle as normal. So I prayed on a chair, this was 3 weeks ago. I am staring to pray normally but my my ankle is no where near as normal. Instead of sitting on my ankle I sit or stand  on my knees, again not a normal prayer position.
The most comfortable position is sitting on the chair, can I go back praying on the chair or preserver with sitting on the floor and praying.
