Q. What are the ways to remove acne scars?

Hi doctor,

I am 24 years old. My weight is 50 kg and my height is 158 cm. I have severe acne scars on face, back, lower back, below the neck and pimples on face. Even after using Benzoyl peroxide there is no change. I have oily skin. I use to get severe menstrual pain up to 3 or 4 days and for which I am using Meftal spas. I have breast pain mostly except the period days and few days following. Also there is a small color difference in the right breast not overall. But, the pain is not specific to this area. I get pain in both breasts. Is it just premenstrual pain or something to be concerned?

For allergy, I am using nasal spray and Allegra tablet. Back pain is present occasionally and not severe. I have hair fall and thinning of hair from scalp and dandruff problem. When I oil my hair for dryness I get more pimples. What else can I do for dry hair, hair fall and dandruff? Occasionally, I get a lump below the lower abdomen on the right side. A doctor once made me cough and tested, the lump was not formed. But, he said with symptoms it would be hernia. It follows with a mild pain there. Also, at times I feel like I have to give pressure while urinating.

Will these be a symptom for PCOS or endometriosis or any hormonal imbalance? What are the ways to help remove acne scars? Is baking soda a good choice? Or any other home remedy? I apply lemon juice on face, even baking soda, but nothing is working for the scars. I drink milk twice a day mixing Amul pro whey protein powder. Does dairy product cause acne? At times I get a burning sensation on body, especially after afternoon sleep, and also at the back of neck when my hair touches. Is that due to severe back acne scars? How can I take care of the diet for the problems concerned? Can you suggest me a good sunscreen for my skin?
