Fitment issues don't go away on their own.
In general if something is wrong (like your fitment) and you take a break but don't change anything, the original problem won't go away. Your fitment problems will still be there.
Numb feet can also come from soft shoe soles (like sneakers), anything that allows you to cut off circulation to the bottom of your feet.
Shoulder/hands stuff - usually caused by too much pressure on hands/shoulders (of course). Typical cause is a saddle too high and tilted down to protect the jewels (threatened in the first place by the too-high saddle height). Proper saddle height (and a more level saddle) will solve this almost instantly.
