Burning nipple pain 8 months after breast augmentation and mastopexy. Is this normal?

Hello, I got breast augmentation with a lift done over 8 months ago. I have silicone implants, and occasionally I was getting a shooting pain here and there. But for the past two weeks, I have been feeling a constant burning pain in my left nipple. Pain level is 2 out of 10, so I didn't make it a big deal. However, it's not going away. From the outside, both of the nipples look the same. So, it normal to have that constant nipple pain, or should I contact my doctor?
