Hi
I ran my second 10k this morning and now my knees , especially the right , are hurting quite a lot walking and going up and down the stairs, I think my running form is ok but I just don’t know what the pain is , I have arthritis in my fingers or what I’m sure is that as no actual diagnosis ( had an x Ray they said nothing 🤷♀️) so is it normal for knees to hurt after starting to run further? Any advice gratefully received 😊
