Breast pain after laser hair removal on breast and nipple

I have hirsutism and for that reason I am getting laser hair removal on my breast, nipple, neck, legs, butt and bikini area. I did a laser hair removal a year ago in late May and after the session, I went on holiday and the temperatures were on average 38 degrees and 26 degrees at night for three months. I protected myself from direct sunlight but when I went outside, under heat, my left nipple and left side of the breast ached. Could heat and laser cause this pain?
