[|Human|] I have an area on the upper part of my left calf that is red, swollen and warm to the touch.  I can feel a lump and it hurts when I touch the lump.  I dont see any bites or broken skin.  I had vein procedures 3 months ago.  Could it be a clot?  I have no pain in my leg other than that specific area.
[|AI|]  Welcome to Chat Doctor. 1. The history and symptoms suggest possible cause could be post-operative infective changes at the site or adjacent to that area.2. And next possible cause recurrence of the venous pathology which you operated for. 3. In this case after examination - an ultrasound examination will be the investigation of choice.4. The ultrasound will exactly identify the nature of the lump, its source and extensions, in case of vascular channels identification of case, presence of lump and flow will be detected.5. Sugget to visit your GP and request for an ultrasound and Doppler study for the limb - the treatment will depend on the findings. Good luck. Hope I have answered your query,anything to ask do not hesitate to ask.http://doctor.ChatDoctor .com/doctors/ Chat Doctor.
