Has anyone ever had this? It's a sensation I've felt probably 2 dozen times throughout my life but several times over the last couple of weeks. If I breathe shallow it's like it can be managed, a bit like a stitch. But you need to take a good full breath in to get rid of it, the sharpness intensifies and the bubble "pops". Usually under the ribcage.
Has anyone had this before? I'm 37.
