Hi Marie, and welcome to NeuroTalk.

There is a condition that can occur after a trauma, and the foot is a very common place. It is called RSD...and can become quite long lasting and painful.

We have an RSD forum here where you can ask questions:

However, if you have Raynaud's you can try a simple thing, which is Epsom salts soaks. This provides magnesium to the blood vessels and helps with the circulation.
Don't use hot water, but use tepid lukewarm instead. If you soak in a bathtub you'll need about 6-8 ounces if you fill the tub past the ankle. In a smaller dish type tub, you use less. Like 3-4 ounces. Soak for about 20 min to 1/2 hr 3 times a day and if you get improvements, that would be a sign that you need ORAL magnesium supplements. Many people are low in this mineral and I have a thread here explaining how to choose a good form, and how much to take:

You would start aiming at 1/2 the RDA or 200mg elemental daily.

Inflammation from any trauma sometimes upsets the tissue and the cells there make inflammatory chemicals to heal things up.
Some of these constrict blood vessels and some expand them. If you are out of balance and don't eat foods containing the building blocks to avoid inflammation (Omega-3 fats like flax oil and fish oil) and you instead eat high amounts of Omega 6 fats, you can get stuck in an inflammatory spot, where healing is difficult.

Also don't wear tight socks or tight shoes. This may impede the circulation too.
