Around the beginning of Summer, I noticed some type of lump/swelling on my inner
elbow, right above the crease on the side closest to
my body with palm facing up.
My doctor said that it must be a hematoma and that I might have bumped it without noticing. After a several months, the swelling decreased and nearly disappeared, but it has recently come back. There is no discoloration and no lump can be felt beneath the skin when my arm is bent.
