I have a white cauliflower like brown patches in my vagina , and brown spots on the walls of my vagina, what is wrong with me?

Need to examine: It is not feasible to provide a meaningful opinion without examining you and your symptoms warrant evaluation by a physician. Your description suggests genital warts and it would be prudent to see a doctor. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. Get HPV vaccine, if you are under 27 years of age.

Get seen: Most often these are the large "condyloma acuminatum" genital warts that one can get from the (actually less dangerous) HPV strains. They're easily removed now and if they recur, too. We do want to be sure they're not cancer, so it'll be important to get checked. Best wishes.
