I sustained fractures on my patella and calcaneus (ankle) this cold weather makes it hurt! what do you recomme

Both of these bones have joints lined with cartilage, smooth cartilage is called hyaline. When the bone is fractured, it frequently also injures the cartilage lining the joint. It heals too, but with a less smooth, durable lining, called fibrocartilage. This can wear out or become rough. This is called osteoarthritis. I would suspect this is the condition causing the ache in cold weather. Take Aspirin compounds, or tylenol. Not a cure, but rather, treats the pain and inflammation.

Ouch... that's a different kind of pain than anything else, isn't it?

I had a double fracture of my wrist - though it was many years ago (over 20) it does hurt in the damp and cold weather.
I'm sure that since your fracture was in an area that carries your body weight with every other step you take... it probably hurts a lot more than my little wrist does.
I find that when I keep the area warm and well covered when I'm outdoors, it helps a lot. So does taking Tylenol or another pain reliever when it begins to act up.
I hope this helps you!

anitinflamatories, and keeping it well covered. just wearing a pair of warm socks, and a pair of warm pants , tights, or long johns seems to help my arthritis, which is probably what you now have starting . Oh, and if you have cold floors, wear shoes or slippers indoors.
