You seem to be doing fine! I could barely walk half a block the day after I got my gall bladder out, and just about fell off my bike 2-3 days afterwards as I was trying to bike to the library (I wasn't supposed to be driving, but I thought biking would be OK....duh!) Take it easy! If you don't recover properly now, the whole process will take a lot longer.
LOL...... Trust me, i've been avoiding the urge to do more. The bright side of it being my shoulder is that it doesn't affect walking much (just slower for now). Not a ton of energy yet, but getting some walking and slow spinning on the recumbent bike in makes me feel better mentally.
