I am now 3 months post op out of a right knee ACL reconstruction and a medial meniscus repair. Thus far I have had nearly a flawless recovery, but we are just now starting more intense excercises. The past couple of days from time to time my knee has this dull ache in the middle-back. I do not feel like it is a 'bad ache' I feel as if maybe I have just overdone it a bit and need to rest it up. I mostly came here to talk with others about it and soothe my mind about the topic so I can quit worrying about it. It has also been stormy and cooler weather these past days which could be part of it. So I guess what I'm asking is this part of the healing process, or has anyone else experienced such?
