Swollen legs and feet?

My legs, feet and ankles have been swollen for about a month now. I had a pulmonary embolism last January and was hospitalized twice. I went to see my so-called cardiologist one week and a half ago and he acted like it wasn't a big deal -- even acted like he had some sort of personal issues going on. I told him I was getting fevers at night and severe pain from the swelling and that I also am having heart palpitations. He put me on the 24 hour holster; later was told by "oh some ppl have this PVC thing, etc. etc. I will never go back to see him again. He had been very good to me during my illness last year, but he really upset me this time. So I called my pulmonologist who told me to go to the ER, but I was NOT doing that...am not sitting in emergency room for hours. I have no patience. So I went my dr's office (didn't see my PCP) and I had an infection (woman stuff); and she didn't even look at my leg. Two days later, I go see my regular PCP, he does urine, blood work and doppler test, but he puts in order for test on right leg only and it's both legs -- stupid to me. No clot was seen in rt leg? so i called complaining and asking why no test done on left leg. Rec'd call today for me to go to neurologist and I asked the nurse why would I go to a neurologist for swollen legs, ankles, feet, etc and she says it could be some kind of nerve damage. Okay, so now I'm at the point that I am going to sue the cardiologist. Why must I always speak to the nurse and not the doctor? I am going to call my pulmonologist tomorrow because I just don't get what the reasoning is to see a neurologist for my condition. HELP. Has anybody heard or experienced such. Are my doctors quacks? I have diabetes 2 also.
