50yrs old female, active, not overweight, walking daily 4 miles ( to work and back)
On Friday evening I noticed that my left knee feels a bit weird , it sort of felt like it needs a click.
Yesterday it got worse, it hurts now mainly behind my knee and leading down, I would say it’s the back of my knee and back of my leg.
Any idea what it could be like this?
I did no any running or any unusual activity, just walking as usual around.
When I woken up today it felt better, I actually thought it’s gone but it crept back in, now I feel like I can’t even walk.
Does not look swollen or red or hot..
