I have a large lump, about the size of a silver dollar, and it is movable back and forth (slightly) but not up and down.  It is swollen in the tissue around the lump, warm to the touch and has one or more large veins going into it.  I have had this for more than a year, and it bothers me, but doctors do not seem interested.
Hi. You're pointing / mentioning the site of the ump would have helped me more. Anyway, from the history you have provided this looks to be a lesion which needs to be excised and subjected to histopathology examination. Prior ultrasound with color Doppler can tell us a probable diagnosis so that a proper care can be taken. Hematomas can bleed far more than any other lesions so the need for pre-operative investigations. Go ahead, change the Doctor. Better visit a surgeon, who would be interested in getting a proper diagnosis and giving you a proper treatment.
