Hi I had a horse fall and got a concussion and hurt my leg as well. the doctors did a xray and saw that the leg was not broken and let me go but i had what i read as a pitting edema from my ankle through my entire calf for about a week before I went to the doctor and had a weird purple black spot on my leg as well. After they misdiagnosed me they decided that they would cut open my leg to drain it except not alot of blood came out and they saw that there was essentially a huge air bubble in my leg. And for about a week they kept stuffing it with gauze and pulling it out so it would close right. i forgot when they said I had and I was wondering if you could tell me
