So this morning I woke up and realized I would get a sharp pain on my left side near my heart if I lied on my left side. If I’m on my back or right side I have no issues. If I lay on my left however it starts to hurt again. I think it has gotten better over the day. I've felt lightheaded a couple times today but for not very long. It has only started to hurt If I’m laying down on my left. Don’t know if this is something serious or just me over reacting.
