I dnt know....I just thought it was because of the milk ducts were getting ready to start with that white sticky stuff.
this may be totally not what youre talking about but i get a weird tingly feeling on my back left... i guess ribs?? like if my boobs were on my back, itd be my left boob tingling. ive had it for a while and just thought i was crazy. but its tingly right inside where the shoulder blade meets my back. itll tingle for a few minutes, then go away. i wonder if our tingles have anything in common???
funny thought- based on what Silliekid06 said about milk ducts getting ready- had an image of having to breastfeed with my tingly shoulder blade... weird, i know..
I don't know if it's the same, but sometime I get this like bubbly/cold feeling on my left side. I just ignore it as it goes away very fast.
