Suggest Treatment For Broken Toe And Pain In Leg After Injury

about four months ago I tripped and banged my toe and top of my foot on a chair. Since that time, apart from having a broken little toe which has since healed I have experienced first weakness then pain in my leg. I cannot sit, stand or lay down for any length of time without discomfort. Now the leg feels heavy. I have had osteo-arthritis since my twenties. I was wondering if it could be a BLOOD clot.
