Thanks.. and how is it diagnosed/treated?

This is treatable, I see.. the useless neuro I saw yesterday told me immunoglobulines may be effective, although he didnt believe it was useful. But he was at loss, so I dont know what to make of it. Gonna see another one next monday.

Muscle wasting can happen from pinched/entrapped nerves too, many with severe TOS can have it happen and sometimes a claw effect if severe enough and long term..

I would start working on postures and getting the head/shoulders back and down to see if this helps a bit or not.. you can do this on your own while seeking other dx & tx..

I posted my album link with some simple self help ideas previously.
I would suggest doing those many times a day.
If pain increases then stop, or ease back to a less demanding positions, like the yoga corpse pose..

If a nerve is pinched/entrapped, which was also the idea of my physio, it would be visible on MRI? So that the right points would get targeted with any necessary therapy.

Drugs-induced?
 

Not sure if this is related. Around 4 years before the whole problem started, I was diagnosed with severe depression and was put on antidepressants. 2 months or 1 month before my right hand just dropped down, I changed antidepressants from SSRIs to an older tri-cyclic one (don't remember the name), which I didn't tolerate well. Could that be somehow related?

The only potential, clear pattern I see in my health history, would be gluten intolerance or it. B 12 deficiency. I saw a doctor once for chronic fatigue when I was 16, and got a huge depression years later.

Many of the TOS issues don't show up on MRI unfortunately. If a bony or some anomaly then it should show .
Makes harder to get a knowledgeable dx..
plus if laying down for MRI the compression is usually less as it could be something due to being upright and postural.

Sometimes it is not a large/main nerve that is involved but smaller nerves.

Actually an expert /advanced PT should be able to evaluate and test hands on to track it down , often more cost effective than imaging .

Hi aneczka. Regarding your hand.

I saw your post here just now about muscle wasting.

I had a pinched ulnar nerve (cubital tunnel syndrome) many years ago and that certainly changed the way my hand looked.

Lara, it's just .. that my both hands are now severely affected, not just one. How can you get your both ulnars pinched? In a distance of 7 years? I think something more creepy is going on. I would like it to be just something like that, mechanical-sounding, which can be corrected. How did they diagnose it?

I understand. It's maybe not related at all. Of course it would be possible to have trapped nerves somewhere for a long time, but why I don't know.

This is old but it explains some more about cubital tunnel syndrome. I'm not saying that's what's going on, but it can cause wasting in hands.

If I was in your position I'd be wondering about autoimmune diseases.

Oh, and in my both hands, it was thumbs that got affected first, and are worst now. It could be some other nerve so.
