My stabs turn into feeling twinges of cramps and just like migrating stabs come and go so does this! I getthen under my arms too ( soo painful)

I want to ask if this is like sfn. My arms feels like they are tearing. And even movement makes the sensation worse. It's like extend tightness and burn and I can't touch one arm with other or it gets worse.
Every day is different. I even have th twitching in my stomach like baby kicking.
And can induce it by sneezing.

Sorry for writing so much. It's almost like therapy right now! I feeli like a ticking time bomb and in soo much pain.
