Question, as I look back on events in my life I remember about 10 yrs agp tearing my Achilles’ tendon while playing flag football. This was before my chronic back pain. When I tore the tendon there was no pain. Nothing, it didn’t even ache. My son was with me and I wonder if my brain had not sent the pain signal because I didn’t want to alarm him. Should there have been pain? There was definitely tissue damage. I remember a lot of people being surprised that I didn’t have pain. Any thoughts?
