Thanks for your query.You had red spots on glans penis
ans base of the penis 3 weeks back which were most likely due infection of the Glans called as Balanitis
.which has subsided .Now you have noticed red spot on abdomen and one on scrotum
These are most likely due to infected Hair Follicle termed as Boil.Please take some antibiotics like Doxycycline and anti inflammatory rugs like Diclofenac
twice daily for a week It should subside with this treatment.
