Pain under left ribs...

Jen
Anyone experience what feels like a big air bubble under the bottom of the left ribs? If I laugh or twist it feels like it's getting squished which is very painful, then a pain shoots up to my left collar bone. That pain feels like a nerve shock.  I've read people had similar but can't find ways to help with it. I'm 5weeks almost 6 and it's been 2 days now.
