Suggest Remedy For Cluster Of Bruises On My Thighs

I've been getting unexplained bruises on my thighs. At first it was just one but everyday I have a new one. They are all in the same area and some of them are in clusters. Today I noticed two more on my other thigh and one above the knee.I've also been having terrible leg cramps in my right leg. My right leg is also the one that has the most bruising. I'm worried, could there be something wrong?
