its more of a constant and nagging pain, some days more than others and on different places. today on the knees, tomorrow on the waist, next day on the ass, then finally all places combined. then next day you feel almost nothing. then next day it's back. the worst is that it keeps you from taking long uninterrupted sleeps. i take many short naps during day and night. each nap typically lasts 1.5-2.5 hours. im super happy the nights when i sleep 11pm to 6am straight, but these have been rare. in a few days the pain was intense to the point i began speaking quickly otherwise the pain would interrupt what i was saying by completely moving my attention to the pain itself.
