<s>[INST] I fell a couple of days ago, I thought it had broken both my left leg and arm.I had it exrayed nothing broken, but it is such a very bad bruise, I am a deep purple from my panty line to my knee, that is until today, now it is so hard in one big area on my leg, with little knots protruding on down my leg in several areas. The place that is one big hard place is sorta numb, except it has like rough ridges that has formed at the one side of it. It has been throbbing and very painful.also it is turning blue below my left knee and my knee feels like it is going to buckle up from underneath me when I stand and or walk. Should I return to my primary dr? Can you give me any answers as to what you think? [/INST] Your symptoms suggest that you have severe soft tissue injury in thigh muscles. Such severe injury causes collection of blood under the skin that causes purple bluish color to skin. You need not worry. Ice, rest and non-irritant analgesic gel will subside the pain in 5-7 days. The purple bluish color will fade away in 2-3 week. Hope this helps. Hope this answers your question.
