For about half a year now, I’ve had this strange pressure feeling that keeps popping up under my left breast/sternum. I don’t feel a bump and lately it’s lasted for almost a month. It doesn’t hurt, just moreso annoying pressure that won’t go away. Feels like someone is pressing a finger in that area if that gives any context. Anyone had this/know what it could be? Can’t really find anything online when I look this up.
Also I feel it at night sometimes and sometimes I don’t. I find that when I don’t think about it.. I don’t think it’s there. When I start thinking about it overnight I start to feel it. I’m in my 20s and workout regularly and eat healthy for the most part.
It could be nothing or many things, including anxiety. Are you perhaps sleeping with a hand tucked under you, or a hand with a ring under your breastbone? It could be you are rolling a bit, putting pressure on that area, making it a bit sensitive.
