I'm worried now. But yes . A doctor for the discharge?
An OB/GYN MD or Family Practice MD can do vaginal exam and cultures on you, to determine the cause of your colorful discharge...mostly likely the culture will reveal an STD (sexually transmitted disease) or at minimum bacterial vaginosis. If positive for an STD, it will be reported to your local County Clinic to ensure they contact all of your sexual partners to get them treatment as well. In the interim, it's very important to NOT HAVE UNPROTECTED SEXUAL RELATIONS with anyone!
As far as the oily hair, it could be related to your diet, your shampoo or frequency of conditioner use.
Oh lord. Yeah I read and everything came up to std. I'm married and always try to use protection regardless. But thanks for that I will have to go check that out.
