Help getting rid of chub rub!!?

so i run winter and spring track. over the past summer our field hockey team got a new trainer to train our fitness. basically she made my thighs bigger than they were. there more muscular but i hate them. i have never had chub rub before and now i do. I am so mad. Springs coming so im breaking out the shorts and skirts and bathing suits and nothing looks good. advice to loose chub rub before summer! little more than two months!
