Hi My Name Is Angel, I Am 19 And Weigh

Hi my name is Angel, I am 19 and weigh 130lbs. I have asthma and scoliosis. However, about a month ago I got a large boil under my right armpit. It's popped and days after multiple lumps have appeared on my right and left armpits. Some look like boils as well. I also have had frequent urination, like more that 3 times an hour when I'm awake and it's hard to hold. Do you have an idea of what it is?
