Extreme Swetting

High (cold) sweting indicates on high blood pressure

Sorry

I don't agree with bangertom's answer. The commonest symptom of high blood pressure is no symptom at all. Most people with blood pressure problems are completely unaware of it.

High blood pressure symptoms are quite wide ranging and you can read more about this here:

Low blood pressure again often causes no symptoms at all.

If sweating is a major problem for you then it's probably worth visiting your doctor for a check over. You may need some blood tests done. Often no cause can be found for excess sweating but issues like diabetes and thyroid problems can sometimes be behind it.

Go get checked over.

Hope this helps

I think its a good idea to get a check over if you develop any new persistent symptom

There are so many complex things that happen in our body that you just cant rely on question and answer sites to make a diagnosis

No, it doesn't.  By "extreme sweating", I presume you mean "sweating like a [insert farm animal here] no matter what the temperature is".  A lot of people have a problem with this, and it can often be tied to medication (anti-anxiety meds especially have this problem) or diet (spicy food has a tendency to open pores) or hormonal levels (in women undergoing menopause, this syndrome is known as "hot flashes") or some combination thereof.  If it makes you uncomfortable, I'd bring it up with your doctor.

Can be a result of both

There is a condition where the sweat glands in your arm pits simply begin to over produce sweat.  I have heard that botox injections there can help the problem for up to 6 months, but it is painful and you have to keep doing it.
