From the back of my heel up to my ankle it feels like blood is being slurped up my leg. Is this something to be concerned about?

Yes. never heard this complaint before…slurpeeitis….sounds like something out of a 7-11 movie….on a more serious note….it could be an achilles tendonitis or neuritis…..see a foot and ankle doc...
Describe again? Please describe it again, is this pain? Is it red? Swollen? It's a strange description.
