Foot numbness + leg pain + new visible vein = what?

I'm a bicyclist. One day I noticed numbness in the ball of my left foot. It felt like when you cross your legs and temporarily cut off circulation. I figured I just had my cycling shoes on too tight. But I also started noticing pain in my calf. I took a look at my leg and found a new dark vein had appeared on my calf. My initial thought was I had either a blood clot or a burst vein in my leg. It definitely suggested some kind of vascular issue because the numbness and the pain and the vein appeared simultaneously. But the symptoms don't match phlebitis.

I had an MRI yesterday which showed no vascular issues or muscle tears or anything else. This has been going on for 5 weeks and I'm getting tired of it.

I know it's a long shot to ask this on YA, but do you have any other ideas what this might be?

You should be taking a peripheral test for nerve function. Periphral neuropathy is a common nerve disease which causes numbness on the balls of the feet. it is often accompanied by sharp nerve pain in the foot area and some times severe burning. Could be a pinched nerve or something somewhat more serious. If it persists have a neurologist look into it.

hmm old age? hehehe seems our cells inside and out go thru changes as we age. yours may be something that is genetic....check with family members. it could be a bruise or a vein popped while you were not hydrated enough? suggest apply a topical sport creme with salicylic acid to your entire leg...throught the week alternate areas of the leg and thigh and heel and knee. (not the entire leg at once). (salicylic acid =aspirin...check with your doctor regarding this if you have allergies, taking other meds, etc) warm wet compresses and gentle massage should help better your circulation. try sport drinks while cycling.

not sure about the numbness, but if youre over doing it...maybe cut back on the cycling some. also, check with your doctor about diabetes or regarding heart health.
