Have any of you fellow blood thinner users ever developed a large hematoma? I typically only develop the small bumps under my skin that go away on their own within about a week. But now I've developed a larger than usual bump under my skin about 3" or so in length. It's got me worried sick. It is soooo sore. I see my dr Monday and will let her know about it but I am worried sick that they may want to try to drain it. Has anyone ever dealt w a larger bump like this from blood thinner? What helped you?? I'm on lovenox twice a day while I'm pregnant.
