I have a cyst-like lump on my arm ...right in the middle of my tricep. It s under the skin, about 1/2 inch across and maybe 1/4 inch up/down. It does not hurt and can be felt but not seen on my arm. I ve been on heavy duty antibiotics for an infection in my jaw, so I don t think it s an infection. Any idea what this could be? Should I be overly concerned?
