I had foot- ankle and heel pain. Then my calf started to hurt. Swelling near and blow the ankle. Seen doctor and had X-ray nothing found. Thought part of it might be Plantars Fasciitis and put me in a boot and inflammation meds. She was concerned about a blood clot but no history so nothing more done. Swelling went down and now I can tell more of where I have pain. Heel and calf areas not joints. I have been applying ice to calf as well as using the hot tub but I still have some pain. I also feel a tingle or tickle in my leg but it happens randomly. Sometimes at rest and sometimes when up and moving. I have noticed a small knot under the skin on my shin and I assumed it was from the boot which has the air chamber and the pump is on top of that area and it rubs. So I thought the knot may be from the boot. I didn't notice it before the boot but it's not noticeable by sight. But after thinking about it I'm more concerned. It's tender to touch but no color change. I also thought at first that my calf pain was from trying to compensate for my foot pain. Leading up to this I had excersized the 2 prior days and one of those I went up and down stairs. With all this said should I be concerned about this knot and calf and heel pain?
