How long has this been going on? Just one side? I do have weaker side that I get injuries on especially from things like days where I have excessive walking in the wrong shoes (ya, for me, shoes make a HUGE difference) or I exercise hard (which is at all right now as I'm out of shape) or just my clumsiness (popped my hip/glute muscle awhile back walking in my back yard and got foot in hole in grass, sigh). Nothing like that has happened? I remedy lots of that with stretching, icy hot and rest. Plantar fasciitis also comes to mind. https://www.mayoclinic.org/diseases-conditions/plantar-fasciitis/symptoms-causes/syc-20354846 It often starts in the back of the foot. (have had this as well, started in my heel). It hurts. If all of that can be ruled out, then yes, you need to be evaluated for DVT. When you look at the symptom list, you really only have the pain. Your leg is not swollen, correct? https://www.mayoclinic.org/diseases-conditions/deep-vein-thrombosis/symptoms-causes/syc-20352557 Do you have long periods of sitting and how old are you? If you don't mind me asking.
