Hi there ~
It is understandable that your wanting to know about your condition is not uncommon. Having a headache and body pain
along with red spots near your vagina and burning urination could all suggest that you have a urinary tract infection
. If that is the case please get a urine routine examination done and if there is anything detected you need to get a culture and sensitivity test done and get started immediately on antibiotics for the infection. The spots on your vagina seem to be infection as well and will go away sooner or later, and this is not a cause of concern. I would advise you to see a gynecologist to get yourself tested and have a pelvic examination done. I hope this helps.
Take care and have a lovely day !
