i am in remission from lung cancer however I formed a blood clot in my leg and it traveled to my left lung so for the pass 2 months I have been giving myself shots in the stomach to dissolve the blood clot which they said it would take about 6 months to dissolve. anyways I have some areas that are lumps from the shots. Is this something to be concerned about? It doesnt hurt or anything but it has me a little worried. I dont see the Dr. till the 15th of April so I just wanted to get some opioions about what people think it might be?
