Where did you first hear the tingling sensations? I felt the tingle as if near my ribs and now every evening it starts to twitch there. Maybe it's just the tingle or something else? Tell me what the tingle resembles and how to understand that it is exactly them? P.S. I have never felt anything like this near my chest and ribs before) Thank you all in advance for your answers ❤️
