[|Human|] Thanks. Three weeks ago I fell on my bike. This resulted in several bruises which have mostly dissipated. A large lump is still present on my lower right leg however, on the calf. Would this be a hematoma? I am a 58 year old male. I am in mostly good health, but may have ChatDoctor.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. Yes this is more likely to be hematoma. But better to get done 1. Clinical examination by orthopedic doctor 2. X-ray of affected part 3. Ultrasound examination of affected part These all are needed to rule out fracture and callus formation. At your age of 58 years, osteoporosis is inevitable. And fracture is common in osteoporosis bone. So the swelling can also be due to fracture or callus formation. If fracture is there then you need operative correction. So better to consult orthopedic doctor and discuss all these.
