Hi people,

Seeking for your experiences on how to recover from knee and ankle injury from running. I know that I have to rest these joints, but it feels like it's taking too long to recover I feel bit scared.

Bit of background, I'm just half or 1kg overweight mid 30s. I run for health, no serious target or anything. Usually 30 minutes in the evening every 2-3 days while waiting for evening rush traffic to clear. Started this habit feb this year.
I might have pushed it bit too much for me when I try to run with faster pace last month. It has been like 3 weeks now with this pain.
It wasn't that painful in the beginning - just dull pain in front of knee and upper knee when I really strain it, so I try casual walk around taman, to my surprise it became worse lol. Now my left ankle is all stiffed up. 

And what other exercise I can do in the evening that doesn't involve walking?
