From time to time I get a sensation of tightening behind my sternum, just where my valves are situated. It isn't uncomfortable, it is more like a little twitch. It only lasts a second, like a small painless contraction. This is not a daily occurance, it could happen several times then none for a while, days or even weeks.
Is it just me or does anyone else get something similar?
