I've decided to transition back into running, for no other reason than I want to. I did a 3 x 2/3 mi jog yesterday with 1/3 mi walk breaks. Pain was 0/10. Pain last night was 0/10. Pain this morning was 0/10. This afternoon, I was going to do something similar but a 2/10 achilles pain began within about 1/4 mile. I then decided that walking would be fruitless. So I decided to run 1 loop of back cove, easy, but without walk breaks. After maybe 1.5 miles, the pain settled down to maybe 1/10. There were hints of it disappearing all together, but these were short lived.
Now its 3 hours later and I have 1-2/10 pain simply walking around. Do I go back to old school and not run, or do I have faith in the new school and run (ez) through it? With the exception of my metatarsal stress fracture, I've largely run through my injuries, with at most a few days off. This includes multiple bouts of minor plantar fascitis, calf strain, achilles weirdness, posterior tibial tendonosis, "piriformis syndrome" (both sides but at different times), and osteitis pubis. But these running injuries didn't really hurt while running although the OP hurt to cough or sneeze and the piriformis hurts to sit. Running through the injuries has taken a variable amount of time. The OP took 2 whole seasons. The left piriformis too 2 whole seasons (that is, the injury lasted through ski season despite effectively not running for 2-3 months).
I can't say I'm very optimistic about my achilles. First, it's a weird location. While running, it feels like plantar fascitis, but I'm fairly convinced its insertional achilles tendonosis/itis, that is where the achilles joins the heel bone. I don't look forward to running with this all season, or simply dealing with it walking around. But, I'm an experiment of one and I'm impatient to run. So inflame on!
