Hello bella lucia,
nothing to be overly concerned about.
Aches and pains can be par for the course.............
Dr Shelton...
"Aching Limbs: Besides pains in the back, usually in the lower spine, there frequently develop in the early days of the fast, pains in the hips, pains at the base of the skull and aching in the limbs, particularly in the joints. These pains and aches are often very annoying, but seldom last more than one or two days. They develop chiefly at night and cease during the day."
"Catarrh: A cold may sometimes develop near the beginning of the fast. Soreness in the throat may also occur, though rarely. The elimination of mucus is almost always increased in the early part of the fast in chronic "disease."
