Pain In Nipple & Areola. This pain?

For the past 2 months, I am experiencing pain in my nipples and at the lower end curve of areola. It pains even if I walk or touch it gently with my fingers. There are burning sensations also around the lower half of areola. Initially, the pain was slight but it has got worse. The nipple & areola skin also becomes very dry but I have applied coconut oil, moisturizer, and soframycin but they are not helping. I am taking full care of hygiene and wearing bra most of the times but nothing is helping. At this moment, the dry skin is slightly better but the pain is very bad. At present, the pain is only in the right Nipple and not the left one. I am unmarried so what could be the reason for the same and how can I treat this pain? Please suggest. Thanks!
