Can someone explain the connection between sweating and neuropathy? I know there is some connection to the disorder, but never knew the real reason why. I know sometimes people will also sweat due to the side effects of some of the medications taken for neuropathy. Thanks....

For people with CMT the body cannot control temperature very well. Therefore, we can sweat at night, or in the day, etc. Nothing to do with hormones or medication, etc. either.

I don't know why with other kinds of PN.

Tho it's technical at first to navigate? It is worth it....

On the left index click on 'Diabetes in Skin disease' then be sure to click on the abstract and the introduction. Then go on down the lists...
Essentially, your peripeheral nerves aren't sending ALL the right messages to all the right other systems in your body.
Most who have varied PN's have a COLD senstitivity.... But it also can work the other way. It's not exclusive one way or the other.
I'd not really realized it until I talked with a distant relative who had MS and had the 'hots' all the time... that's when I searched and found this site.
Yes, some meds for other issues can cause excessive sweating at times - I'm on a aromatase inhibitor that is a real tiger in this quarter! [For post cancer treatments] I'm sweating like a racehorse at times and yet my feet are icebergs - go figger? I also wear finger tip less gloves to keep my hands warm half the day. Doesn't matter what the temp is inside or outside!
As for meds being the culprit? Do look up all the 'prescribing information' details on each of your meds...sometimes they work together? some times not. Just something to keepin mind.
Hope this all helps - 's - j

--are fairly common with small-fiber/autonomic neuropathy, and part of the reason why some physicians suspecting these will order th sudomotor axon reflex or other sweat tests, to see if the small, unmyelinated nerves that control the opening/closing of sweat pores react as they should with temperature fluctuation.

I am basically frozen feet all the time and know you were asking about rsd to me and many there have extreme sweating but also time of severe cold. I am not sure the reason other then your body not responding correctly and being extra sensitive to outside factors.

I am glad you raised this - I have idiopathic pn and for years have been freezing cold - with raynauds so bad that I get chilblains all winter long... but now have started overheating, particularly at night - so glad to know "it's not just me". sorry - not much help though

I sweat so much, even when other people are cold and yet my feet are freezing, even when the rest of me is sweating. It's very annoying. But I can't wear snug socks and I can't wear shoes that enclose my feet because they cause so much pain and burning so I have to wear sandals winter and summer, and ones with just two straps---Crocs sandals. I have good circulation in my feet, so it's not that. I really don't understand it.

Also, what is "rsd". I can't figure that abbreviation out yet.

RSD-Reflex Sympathetic Dystrophy

This is our RSD forum http://neurotalk.psychcentral.com/forum21.html

In general PN especially those with autonomic PN will have less sweating. If you have PN in the feet you may see less sweating there. (that was my experience)... some of my sweat response has returned however today.

If you take drugs?
Many drugs cause sweating. Opiates, tramadol, SSRI drugs,
NSAIDs are just some examples.

If the sweating is greater after eating, this is post prandial sweating, and linked to prediabetes/insulin resistance and frank diabetes.

You will sweat more during a low blood sugar event.

People with RSD sweat more as a rule because of the sympathetic nervous system malfunctions. RSD is considered a neuropathic pain syndrome too. But it has differences from PN.

With atuonomic neuropathy - I've found that I dont sweat like I should in the intense summer heat of southern calif - and instead have to be very careful as I've gotten heat stroke just going from car to doc on a hot day.... get very faint also quite a bit in the heat and dizzy... all symtoms of heat intolerance - your body is not resonding as it should to the temps and allowing you to sweat because of the damage to the nerves that would normally tell your body how to respond to the temp changes... during the summer I always carry water - not only to drink - but to pour on me to try to keep cooler - cause we have so much hot weather one has no choice but to continue life no matter how hot it is....

As for cold - the neruopathy has affected the cold extremes too - I used to never get cold (and yes, it can get chilly here) - I find that I have to wear socks to bed during the winter to keep feet warm - never did pre-neropathy, and layer more too during the day.... supposedly I have reynauds, but whatever they want to call it - the ultimate culprit I know is the PN!
