I have similar symptoms to some of you, mainly left side, it stated a couple of years ago with what felt like a bee sting in my left upper back near shoulder blade, it would come and go, there was nothing there to see, I did mention it casually to GP when I was there for another reason, he said it was likely to be a pinched nerve, so I stopped worrying ( I do have health anxiety), Fast forward to start of this year when the stinging feeling developed into a dull ache which is also in shoulder, down arm into hand and also armpit pain I sometimes have twitching muscles in arm, leg & fingers/thumb and for the past week, left side neck pain, I also sometimes have a feeling in thighs like someone nipping me. I must admit my mattress is not the best and most mornings I wake up with pins and needles in both hands which goes when I get up, I always think the worst, got GP tomorrow for a check up after gall bladder removal, I am worried about mentioning this as like a few of you say, being referred for scans etc just fuel our anxiety. I must admit, mine has been worse this year since I started Peri.
