numb toes...

[Sleeeppp]

I was wondering if anyone else has experienced waking up with numb toes? (only on the tops and outside of my big toes)... I have been getting this for quite a while (don't know when it started) but haven't really taken much notice of it (and all the sleep specialists Ive seen haven't asked any questions relating to this).

My sleep studies show mostly hypopnea events (AHI 19 or 30 (on back))and a drop in blood-oxygen saturation to 87% (for a short period), bpm 48-100 .
All my blood work is good (no diabetes ..etc)....

could the sleep apnea be contributing to this?

I have been on cpap for nearly a year and the last two months on ASV which has good results (AHI 2.5 to 0).

I have that problem periodically, nothing to do with sleep apnoea and CPAP though.

A couple of years or so back I asked my GP about it, to date I have no conclusive answer to it.

I have a bone chip in one ankle joint that may sometimes put pressure on a nerve in my foot, but that doesn't explain why the other foot also gets the feeling now and then.. though not nearly as often as the one with the dodgy ankle joint.

I also have a bulging and damaged disc in my lower back that may also be the cause by pinching on a nerve while I sleep.

My first thought when reading your question Sleeeppp was that it is likely not related to SA. Have you spoken to either your GP or your sleep doc about this?

With 87% spO2 nadir, it's not from sleep apnea.

If it were me, I would get a duplex ultrasound of the arteries in the legs.
They check flow velocities at 5 point along the leg and ankle.
It's a test for peripheral artery disease.

I had numb toes a few years ago which progressed into both feet. I had tests done for diabetes and was negative. I when to a specialist and after many tests was told that they could not determine the cause and that I had to just live with it. There are medications that deal with the burning sensation and nighttime joint pain.

I would suggest your first stop would be with your GP to rule out diabetes.

My heels, toes, and other parts of my legs go numb. Both arms do as well. I have spinal issues at C4-7 and other issues in the sacral area. The heels have been tingly for, wow, close to two years. I wake up with them getting worse and find that either my head is turned or I am on my back without leg support.

It is possible that during sleep, you are putting a vertebrae out of alignment. When you get up and move around, the pressure on whatever nerve it is, is relieved. If diabetes has been ruled out, the next step I would suggest is having MRI done of your spine. With the feet, it is most likely the lower back.

When you wake up and feel it, make note of what position you were in. And if you think you just shifted in your sleep (as in moved to a more comfortable one just prior to fully awakening). The GP will need to know this.

Same here, just C4-C6...My Lady is like this ,too...but she had a brain tumor and with her diabetes is worse...spent part of last night rubbing her feet...don't help my insomnia or ptsd...lol.
You need to have it checked out...pray it's minor...

I'd put my money on L4/L5.

Thank you for the replies - much appreciated.

(Cate1898) - No, I didn't mention this to either my gp or the sleep doc because it did't seem important/relevant at the time (the sleep doc didn't flag this during the consult).
(PaulaO2) - i will make a note of my sleep position etc to see if this (or my bed) is a factor.
(justMongo... and all) - I'll see my gp to organise these tests...
