It all started 9 or 10 months ago, my boyfriend's foot suddenly starting swelling up and going red. He rubbed it out and he said it felt as if the blood was going back through his body. It was as if the blood had been trapped there, like a blood clot. He ignored it until the same foot same spot went numb for a month or so. He also let that go. Last night he felt like all the blood in his body shifted like it rushed to the left and his right side, arm, everything went limp and numb. When i rushed him to the er they immediately didn't listen to a word we had to say or the symptoms they basically told us, they are not concerned and dismissed us because we're kids. I just want to know whats going on. What is this?
