so after that post, on tuesday i went out and lifted weights ... nothing aggressive ... just some bench pressing, bicep curls, etc. i was fine all day long until the end of the day. the pain in my left neck/shoulder area was extreme. i assume it was a pinched nerve. i could hardly turn my neck and at night, i was in extreme discomfort. it took about a week for the pain to subside.
this sort of thing regularly occurs when i lift weights. i'm just not sure i want go through this again for the 100th time. i may just focus on simple push-ups and sit-ups along with long walks and spinning.
