I slipped and fell on a flight of marble stairs three weeks ago . I had huge amount of bruising which extended all around my back and down into my buttocks . No spinal issues as full range of movement no bladder or bowel issues however I have this huge lump just above my coccyx on my lower back it is visible through my clothing. Can you tell me what it is ? And how long it may remain ? All brusing has now gone Thank you Eileen
Hi ! Good evening. I am Chat Doctor answering your query. With the history of trauma and initial bruising transforming into a large swelling now, most likely a cyst has developed which might be containing liquefied blood in it. If I were your doctor, I would go for an FNAC of the swelling under very strict aseptic conditions and if need be would also go for an MRI to diagnose the origin of the lump. Till then, I would advise you for an anti-inflammatory along with a proton pump inhibitor Chat Doctor.  Further management would depend on the reports of investigations. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor.
