Sudden inability to sweat

I spent most of my life unable to sweat.  Now I can.  It really does make a difference with your ability to cope with heat.

Wow!  I have a similar experience.  I used to sweat like crazy, and now I don't seem to sweat at all and I live in a very hot desert so I have to be very careful.  I went to a pool party, but since the temp was over 100 I had to sit in the shade and keep ice packs under my shirt!  Another weekend, I was working outside (cooler day) for about 45 minutes and my face became purple!  Everyone was very panicked, but I just drank lots more and put ice packs on my face for an hour or so until it got better.  I thought I was having a heat stroke. 

I did 6 rounds of TCH at the end of 2008 and have been on herceptin since....tykerb for the last year.  I thought it was related to the tykerb.  I didn't even thing about my chemo induced menopause.  My onc doesn't seem concerned, but it makes it difficult for me to enjoy physical activity and the outdoors.....unless I can carry enough ice packs with me!!   They checked my thyroid and that and all my blood work is fine, too. 

I guess we are just going to have to find a way to make ice packs fashionable this summer...LOL!!!   BTW - I have family in Tenafly, NJ and we love to visit in the spring and summer - I can see why it is called the garden state....so beautiful!!!  Best to you :>  lisa

You might want to ask your doc about Peripheral Neuropathy.

Symptoms of Autonomic Nerve Damage

Symptoms of autonomic nerve damage are diverse and depend upon which organs or glands are affected.

Autonomic neuropathy (autonomic nerve dysfunction) can become life threatening and may require emergency medical care in cases when breathing becomes impaired or when the heart begins beating irregularly. Common symptoms of autonomic nerve damage can include:

# an inability to sweat normally (which may lead to heat intolerance)
# a loss of bladder control (which may cause infection or incontinence)
# an inability to control muscles that expand or contract blood vessels to maintain safe blood pressure levels.

A loss of control over blood pressure can cause dizziness, lightheadedness, or even fainting when a person moves suddenly from a seated to a standing position (a condition known as postural or orthostatic hypotension).

Toxins

Toxins can also cause peripheral nerve damage. People who are exposed to heavy metals (arsenic, lead, mercury, thallium), industrial drugs, or environmental toxins frequently develop neuropathy.

Certain anticancer drugs, anticonvulsants, antiviral agents, and antibiotics have side effects that can cause neuropathy secondary to drugs, thus limiting their long-term use.

Hi ladies,

I have not been able to see my Onc as of yet. When I see him next I will talk to him about this and I will report back here and share his thoughts.

What's the big deal about not sweating?  I don't ever recall sweating for any reason inmy life.  Even when I was having hot flushes with Arimidex I never had a sweat.  I have never had to use deodorants in my life since I don't sweat.  None even when I lived in the real South!  I never equated sweating as being a necessity for our bodies.  Maybe I should mention this to my regular doc next appt. I wonder where the toxins in my body go to.  Like the other poster, I urinate non-stop all day and even at night  so maybe this is "my" form of sweating.  Very interesting!
