Dry red spot appeared on skin by hip, rash covering my body followed. red, circular, itchy, spots from neck to groin, front and back. help!

From: A viral exanthema, to reaction to a medicine or an insect bite, go have these check, specially if other symptoms develop. Good luck!

Rash: Sounds like it could be pityriasis rosea a non dangerous self limiting rash in younger people. Google it and see if it matches. However, you should see a dermatologist to confirm this and to make sure you are not dealing with anything else. Hope this helps.
