Hi, I had gone through your question and understand your concerns. It may be deep vein thrombosis or so called DVT although this is not very likely. I means that clot is formed inside the big leg vessel. So you need to do Doppler ultrasound to rule this. Vein thrombosis which is manifested with unilateral swelling of the leg, pain in calf and lividity of the skin. . To reduce the swelling from a foot or ankle injury, rest to avoid walking on the injured ankle or foot, use ice packs, wrap the foot or ankle with compression bandage, and elevate the foot on a stool or pillow. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
