I am 22 years old. Toward the end of last week I noticed a lump in my right thigh (near the crease) a few days later I noticed there is a cluster of smaller lumps straight up from this bigger one. They all seem hard and it hurts when I press on them, the bottom and larger one hurts when I walk. The larger one has grown since last Saturday, it is about the size of a quarter now. The only other symptoms I've had (that may not be related) are, Saturday morning I had the symptoms of a UTI- The constant urge to urinate, and the burning when urinating-It was the worst Saturday morning, but lasted through Sunday, by Monday those symptoms seemed to be gone. I have also just felt run down and worn out but my sleeping habits haven't changed, I feel like you feel when you have a cold coming on, but don't have any cold symptoms, besides the right side of my throat be slightly sore.

I'm the type of person that tries to avoid going to the doctor if possible. Is this something I should have checked out? If so, what type of doctor should I see? What types of tests will they run? I can get health insurance, but I don't currently have it, approximately how much would the doctor visit cost (if it's necessary)

Thanks in advance, I appreciate you taking the time to read this.

No one has any thoughts on this? I also wanted to add that these are all internal, I can feel them through the skin, but there is no sore on the exterior of my skin.
