exercise, my walking since a while:
i go outdoor for the first time in afternoon(i try to sleep morning), very heavy chest, heart, spine and shoulders pains, have to stop each 10/15 steps and rest 2 minutes, it is very difficult, after half an hour or one hour, i am able to walk 50 steps to 100 steps and with mild stopping resting, mild pain;
if i go home, and go outdoor again, heavy pain as before until one hour and then much more easy to walk
