Well, I didnt know this but apparently one can develop “frozen shoulder” crocheting. I was working on a new project and tripling up the worsted weight yarn. I was also binge watching the old 21 Jump Street. I didn’t take enough breaks to exercise my shoulder and after 16 hours (two 8 hour sessions) I ended up not being able to lift my arm to even grasp the steering wheel. I went to my doc and went through some physical therapy. My arm works now. Please remember to exercise and take breaks.
Doc said in the first he’s heard of getting it from crocheting.
