Hello. I had four stents put in my heart on 10/2009, and have had no trouble whatsoever since. Ten days ago I thought that I d been bitten by a mosquito just by my shoulder blade as an itch started. This feels like a wire from a stent has come adrift somewhere. This only happens when I m standing but not when I m either sitting down or in bed, and there is no support on my back. Seems like a small prick under my left nipple and at the same time as a prick on my back. I am 76, male, haven t smoked for forty years and blood pressures are usually around 130/70. Cheers.

Hello Tom! Thank you for asking on Chat Doctor! First, I would like to assure you that your pricking complains has nothing to do with your stents, Stents, or even their components cant come a Chat Doctor.  Your pain is so atypical for explaining a possible ischemic myocardial disorder (it is a sharping, positional, migrating and well-defined discomfort). So, to conclude it seems t OBE an extracardiac pain. I recommend to consult with your doctor (GP or internist) for a comprehensive physical exam, a resting ECG, chest X-ray study, and if suspicions are raised, a cardiac ultrasound to rule our any possible pericardial effusions. Hope to have been helpful. Greetings!
