Since April, I have noticed a soft, moveable lump on the medial aspect of my lower left leg, just above the ankle region. One week ago, I started experiening pain in this same leg, from my buttocks down to my foot. The pain is far worse when I am laying down than when I am standing or sitting. I also am a longtime sufferer of low back pain and have also been diagnosed with sacroiliitis. I also have a past history of a single lipoma that was removed from my upper back. Do you think the lump and pain in my left leg are connected, or is the pain likely due to my sacroilitis. I would have seen a doctor months ago regarding the lump, but I currently have no health insurance. Thank you.
