About 6 months ago I fell down and my full body weight landed on the front of my shin against a raised platform. My leg swelled up so I had an x-ray done but was told to just rest the leg. Around 3 weeks ago, after starting an exercise programme, the area of my shin that was bruised and swollen, began to bruise and swell again and appeared red & hot to the touch. My doctor said it was called Erythema nodosum and carried out blood tests. These have all come back negative to anything serious but my doctor has now discharged me. Is this something that will now just keep inevitably occurring when I exercise? Also, over the past few days walking has become difficult on the same leg due to a raised, red sore area on my big toe (similar place to a bunion but VERY painful)....could the two be linked? I am 29 years old.
