. Capsular contracture present on left side and right was normal. Recently had an injury that caused 4-6 weeks of a lot/immobility and weight loss. While laying my dog jumped on my chest and caused a pain. I had a fall to that side as well. I noticed the effected side appeared to be lower (some of which was like before due to the contracture on the left side) but also had burning pains in chest/muscles? Unsure if it is the cervical injury or trauma. Could it be muscle/rupture? Aug 17 yes ago.
