Can a hematoma be removed from my left side(hip)?

On March 22, 2017, a lipoma was removed from my left side(hip). 2 weeks later I went to see the Doctor because there was a painful lump in the same area. She drained blood and fluid, but there was no infection and she hoped it would go down. End of April, 2017 I noticed the lump had grown. Ultra sound showed there was a hematoma that would probably dissolve. Here we are, Sept. 27, 2017 and it is still here, feels larger and is painful to sit, lay, walk, do almost anything causes pain. What is next?
