I Have 3 Hard, Painful, Nickel Size Lumps On My

I have 3 hard, painful, nickel size lumps on my leg all the sudden I got a big purple bruise on the same leg and now the bruise has 2 dark purple lines going through it! I went to the hospital and they said they are not sure maybe cysts (they acted like they didn't care much)
I am also 3 1/2 months pregnant and I am trying to get insurance so I can go to a dr!
