Trapped nerve while sleeping?

Recommended Posts

I feel a little silly asking, but I’ve started to have more frequent episodes of waking up in the middle of the night (or in the middle of a nap) to find that my arm is numb and I can’t move my hand. Usually the left side. It feels like a trapped nerve, as within a minute or two,  I get the feeling back in my hand/arm. But it’s pretty scary while it’s happening. Does anybody else get this? Is this connected to POTS at all? Is this just me sleeping on it funny, or something else?

Do you experience this in certain positions but not others?  For example, I can't sleep with my arms folded across my chest because eventually my pinkie and ring fingers will go numb.  I don't think it is related to POTS, but just a trapped nerve from the way you are lying.

The elbow and the wrist are common places for the ulnar and radial nerve to become trapped or pinched. If you’re sleeping in an awkward position or have these joints bent (like over your head or curled under your body, etc) it can surely causes tingling and numbness in your hand or arm. I almost always wake up at some point throughout the night with a numb or painful hand!! I tend to just straighten out my arm and hang it over the bed to restart proper circulation. I’ve heard that wearing elbow/wrist braces during sleep can prevent the nerves from slipping or becoming trapped. 

Best wishes - feel better!!

I get this from time to time . . . I don't think it's related to POTS per se but, since POTS affects blood circulation, I'm guessing that when you're sleeping in certain positions, the POTS may allow it to happen *easier* because your circulation is already compromised.  Rest easy! 🌛

Thank you for your replies! I am relieved to know this happens to others, too, and you don’t worry about it. I’ll try to “rest easy” as Delta says!

Sounds like it could be a cervical issue with a nerve.

I started getting this as well. It also strangely affects my left side. Usually it happens when I wake up in the morning. My fingers will be tingly and my left arm numb. I also have trouble moving it around as if my brain isn't communicating with it well. I just have to wait till the numbness and tingling stops and then I have full control over it again. I also think one of my nerves in my arm is getting pressed during sleep and that's why this is happening.

@Jwarrior77 As mentioned above, it is easy for the central nerve and ulnar nerve to get compressed. Bruins/Arteries also play a role fore me.

The ulnar nerve is more often a problem for me recently, but I have problems with both nerves on both sides. The ulnar nerve is responsible for pinky and ring finger. I get this more when my arms are bent at the elbow, because it gets compressed at the elbow.

The central nerve is responsible for the rest of the fingers. My central nerve gets compressed at the wrist when my wrist is bent. 

My arm goes numb when my arteries/veins get compressed due to lack of oxygen to the extremities. It doesn’t take much pressure these days. I think it has something to due with a slower pulse (bradycardia), a weaker pulse (PP = SP - DP), lower amounts of oxygen (from pulse ox).

I get varying combinations of two or all three (both nerves and artery compression). The same thing happens to my feet/legs. 

My docs thought this was to be expected because I have small fiber neuropathy, variable blood pressure (high and low), and lower oxygen.

I have suspeted thoracic outlet syndrome, the neurological type and not necessarily the vascular type, which could explain this type of symptom. When I turn my head, I almost pass out. I get a lot of unexpected pins and needles, too.
