Pin Prick Pain during Bloodwork and now have shooting pain on forearm

[bluekay]

I had blood drawn 4 days ago. When the nurse inserted the needle in my left inner elbow I immediately felt a shock trail down to my wrist and then numerous pin pricks at my wrist. It felt like she was inserting numerous needles in my wrist as well. When I mentioned it she said it was caused by dehydration as blood is 80% water and veins would be smaller if dehydrated so I'd feel it more. I accepted this as I hadn't really had as much water that day as I should have. After blood was drawn and needle removed, the wrist shock sensation went away. The nurse told me to wriggle my fingers and not lean on my left forearm for at least 10 minutes when the feeling should go away.
The next day I noticed when I twist my left forearm or move to pick up my almost 2 year old (twisting my forearm to do so) I get a shooting pain, electric shock feeling on the outer side of my forearm. It scares me every time. It goes away when I twist my arm back until the next time I twist my forearm (towards the left). It is now 4 days after my blood was drawn and I still have this feeling.
What is it, will it go away and should I be concerned? I'm now doubting it had anything to do with dehydration.

Hello~I don't think it has anything to do with being dehydrated. I think the phlebotomist hit a nerve and when that happens, you definitely get a shock feeling and pins and needles as well. It is not pleasant. It should be better by now however, I think I would ask the doctor and tell him/her what happened.

Another thought, if he/she hit a muscle, you will have the same pain, but, it will last longer than a few days.

Thank you for your reply. It's been about 2.5 weeks now since it happened and the "shocking/tearing" pain has mostly gone away. Occasionally I will feel slight shocks but nothing like it was those first few days following.
She definitely hit a nerve and tried to explain it away (almost convincingly) with dehydration.
Thank you again for your reply!
