I have swollen lymph node area on my right side...mild discomfort in lower abdomen, and mild joint discomfort in right hip joint, I also had what appeared to be a rash that resembeled shingles on my lower back just above my butt. It is going away, but then i noticed these other symptoms.. Wonder what it could be and if it could be related to the rash. The rash was about the size of a silver dollar and it itched just a little, but never hurt. Wondering if I have an infection or what...?
