I had an undiagnosed foot injury and now my leg is cold to touch with activity

I injured my foot 4 weeks ago.  My foot started hurting on top. I went to a walk in clinic and they did xrays, found nothing, sent me home. Then it started hurting in the ball of foot, toe joints, and top of the ankle. Went to a podiatrist 4 days later, he did xrays, found nothing, wrapped it up, sent me home. His wrapping was tight and my toes were swelling. Ankle was hurting more on the side, and up the outer side of shin bone. One day I was on my feet for a few hours and my lower leg, ankle and foot swelled up. Podiatrist said I now sprained my ankle and did an ultrasound artery test that came back fine. Another week or so later, foot is very slowly getting better but one night after work (waitress) I laid in bed and my foot and lower leg were ice cold compared to my non injured one. It was physically cold to the touch, and my feeling was reduced, although I could feel my pulse in my ankle.

It continued to be cold (not ice cold, but noticably cooler than the other) the next few days, even when I was walking around at work and had been on my feet for hours. But it is not cold in the morning. In fact, on the morning it feels a little buldgy/heavy for the first 30min I'm up. I went to the ER to make sure it isn't a blood clot. They again performed an xray of my foot with no findings and again performed an ultrasound artey test clearing me if any obstructions or high grade stenosis.

Today I stayed in bed all day and it stayed warm. My foot injury has not been diagnosed, as my podiatrist seems stumped and even more stumped at the cold leg. I'm wondering if walking around on my hurt foot/ankle may be causing something to swell internally and obstruct my circulation in that leg, which causes the cold leg, but also explains why it wasn't cold today, having stayed off my feet. Is this even possible?

Throughout the past 4 weeks of also experienced tingling in the foot, nerve twitched, sciatic nerve pain up that leg, calf muscle pain, and my foot and lower leg turn bright red in a hot shower(where my non-injured leg does not).

Thank you for your time.

I unfortunately have no answers for you.  You have done EVERYTHING you can in terms of going to a doctor to diagnose any issue.  Serious issues you'd wonder/worry about with this have been ruled out (thank goodness).  I don't know if there is any type of compression going on leading to this that is intermittent.  Wish you could get to the doctor WHILE it is cold.  Is that possible?  You have a really rough job for an injury with your feet.  I feel for you!

My foot is slowly getting better but I found out a another dr appointment that I now have a heart murmur and an enlarged left aorta. So they're putting my cold leg on the back burner for now. But maybe the two are related in terms of circulation?  I don't know.
