after about a week, I started to feel similar pain in larger area of groin and armpet. Days later the pain slowly generalized
to my whole body. near elbow, my whole leg(mostly inner side), around knee, then spreading to fingers and toes. It does not feel like muscle/joint pain. some ache is within the muscle right above my knee, but some happens on my bones. for example, on the back of my hand, on the finger between joints.
