Ok this is a wierd question, but I'm wonder if anyone has tried this. I obviously can't use a backpack due the broken left collarbone, but I am starting school in about 2wks and will need a bag. I was going to order a Jandd messenger bag before school but I am concerned it may hurt even if I sling it over my right shoulder, as stressing my right shoulder sometimes hurts the broken left. I will be at about 2-3wks recovery when school starts. Need something to carry the books at least the first couple of weeks so I'm open to suggestions.
