Trying to figure out whats wrong with me, I've gotten a Dr appt scheduled, but still trying to do my own research in the meantime.

It started a few months ago. But within a day I started experiencing symptoms in both hands. When I wake up either my ring and pinky finger, or thumb and index finger are numb. Seems that it's usually my pinky side if i sleep on my back or thumb side if I sleep on my side. And like I said it happens in both hands.

Other then the morning symptoms in both hands, I recently started to have semi numb pinky fingers while awake as well. And it gets worse when I'm gripping something tightly or making a tight fist.

Also I've got persistent sore spots in my palm below thumb, doesn't hurt normally, but they are sore when I press on the area, or do something that presses hard against my palm. I sometime get similar pain in other places along my arm or between fingers, but the palm below thumb is the only persistent one.

Best way I can describe it is a sore muscle like pain, like when you just started working out after being out of shape.

TOS is the only logical conclusion I came up with, but just wanting to get an opinion to see if it indeed sounds like it, or could be something else.

Oh and I realize from reading the threads here that it people do have ToS that involves both arms, but what I mean is it feasible that I would start in both arms within a day of each other, or would that point to something else?

It certainly sounds like nerve compression. And it could certainly be TOS, or it could just be at the elbow. The showing up at the same time could just be chance. It's not like bilateral TOS sides are required to take turns.

Are you sleeping on your stomach? This is generally considered bad. A little web searching will provide details.

Are you sleeping with your arms above your head? Also bad for the nerves.

Other than that, see what the Dr. says. Also see if you can find a good PT or chiro to evaluate your posture, alignment, muscle tension and various suspect body parts like neck, shoulders, back, chest, etc. Early in my journey these folks were pointing things out about me that I hadn't been aware of.

Good luck.

I never sleep on my stomach, only back and side. And my arms are always below head level, but I sometimes bend them across my body at the elbow. I've tried paying attention to how I sleep and it seems it happens no matter what the arm position.

The best way I can describe it is my arms are like hyper sensitive to falling asleep. Anything from gripping too tight, to leaning my head on my hand, to pulling up my jacket sleeves to where the elastic is tight on my forearm. All cause my arms to fall hands to start tingling and getting numb quickly and easily.

My interpretation is that you have compression and/or bad circulation to your lower arms and that these other things add to that just a little which pushes you over a tipping point.

Apart from the symptoms - I would also ask, what might have changed at that time or before? Sometimes the body takes awhile to show us there is a problem.

Or any past injuries or accidents in the upper body areas?

repetitive jobs or hobbies?
past whiplash?
sports injuries?
posture changes - head forward, shoulders forward or hunched/rolled

If you can connect these sx with a time or injury it will make more sense, but if none of those things connect then other conditions need to be looked at.

I have bilateral TOS (venous, arterial, and neurogenic). Long story, very short (I hope) . . . I had two herniated discs in my neck, which caused tingling, numbness, and an "electric shock" feeling in my right arm. They had been giving me trouble for a very long time, and the newest MRI showed that they had worsened a lot, and were pressing into my spine. I had a fusion of my C5-C7, and literally the moment I woke up from the surgery, all the bad feelings in my right arm were gone (yes, my neck hurt, as expected). I felt great. While still in the hospital, the day after surgery, the head of the bed was not put upright when I got back into bed, and my head was flung back all the way and I had a whiplash worse than any car accident. That's when my TOS started. I just had nerve studies done and I have nerve damage on my left arm now. It also now feels numb and painful (all at the same time). My question to you is: do you remember any kind of event (falling down, twisting your neck, lifting something heavy) that occurred prior to your symptoms starting? Instead of TOS, it could be problems with your cervical disks (which is what I started out with), so you may want to look into that as well. So many of these neck, chest, and arm disorders have similar symptoms, so it can get very confusing.
