This zinger of pain makes me cry out. Any ideas?

I will see the doctor if I can next week.

The affected area is on my left side, best described as where I put my knuckles where the side of my bra sits. The needle sharp pins and needles episodes only lasts about 5 seconds but it really hurts. It doesn’t happen every day and isn’t affected by breathing in or out. I have health anxiety at the best of times so this is worrying me. I’m hoping it’s just a trapped nerve or something.

Any thoughts on it? Have any of you ever experienced similar?
I will go to the doctor. And I will share with you next week what I’m told but in the meantime I thought I’d ask on her!
