I'm a 60 year old female 5'5" 110 lbs generally in good health. A few weeks ago I had a couple of incidents. I developed a half dollar sized discolored swelling on my left lower leg with under the skin hemorraging below it. I thought it might be lifestyle related ( I sit at a desk for 9-10 hours a day and wear somewhat restrictive short stocking.) I elevated my leg at home, took 1 hr walks mid work day and quit wearing anything restrictive. My leg returned to normal. Then I aspirated 1/2 a potassium tablet one evening and manages to cough all or most of it up. I'm slightly asthmatic and after the aspiration experienced some chest tightness. I went to the urgent care center and the Doc gave me an RX inhalor. It helped a little. That night I woke with a sharp right side chest pain, fairly hight towards the middle of my body. I went to the ER and they took a chest xray. During my 3 hours there the pain lessened and it was the doctor's opinion that it was likely unrelated to either (what I thought was) the leg clot or the aspiration.The opinion was that I had strained a mustle moving heavy things. My blood pressure runs low, around 100, however the systolic was 86 that night.The shallow cough hasn't gone away and last night my chest started hurting in the same general location again and hurts on inspiration. This morniing it's much worse when standing, which I can't do for too long because I'm not taking in enough air and I almost passed out. Could this be mustle strain? I've never had a mustle strain in this location, although I did carry a laptop and gallon of water yesterday evening.

Thanks
