[|Human|] Hi.  I have a blood clot in my right lung post surgery in August 2013.  I am now having severe lower back pain and my physician is suggesting that I get cortisone shots.  She stated this should be safe for my blood clot because they will not fully anesthetize me during the procedure.  I am nervous about getting the shots because of the blood clot.  In your opinion is this a safe procedure in my situation.
[|AI|]  Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. Yes, it is safe to take cortisone shot while having pulmonary embolism (blood clots in lung). But following things should be noted.1. You must follow your blood thinner medicines.  Regular PT, INR report should be done to titrate blood thinner medicine. 2. Make sure your doctor is giving cortisone in the joint and not in the vessels. Intra-articular steroid injection is treatment of chronic joint pain. So it is safe, just make sure that it is intra-articular and not intravascular. And continue your blood thinner Chat Doctor.
