Hi Hopalong80

I can't say for certain but having severe pain like that and when it is accompanied with swelling - this is suggestive of complex regional pain syndrome (CRPS). CRPS is a pain reaction that probably involves the autonomic nervous system that supplies the leg. It is not fully understood but this is not an uncommon reaction to an injury in a limb. It is a real B&*%#@RD of a thing to get. However it generally is self limiting and there are positive things you can do about it. I would seek some help. There is no cure for it but there are lots of things that can help while it runs its course. Here is a reliable information sheet on what it is and treatment available:


Complex Regional Pain Syndrome Information Page: National Institute of Neurological Disorders and Stroke (NINDS)



In addition to the medical treatments describe here physio can often help. Physio can help reduce the symptoms and improve function. So talk it over with your physio.

If this is what you have (and I am not saying you definitely do have CRPS) then don't go it alone. Get someone to diagnose it and get support. You need help with pain management along with other symptoms.
