Finer Blisters NOT hand eczema?

Hi, So for as long as i can remember; when the weather changes and get colder, my fingers peel and crack, just the tips, but it can get really bad. I also get small clear blisters on my finger tips and the side of my fingers. I assumed this had to do with the finger peeling because this too gets worse in the cold weather.
i have noticed a few blisters since it recently has started to get colder, however this morning i have noticed that the finger tips on my left hand have about 5 blisters each. It's not particularly cold today, and it wasn't bad over the weekend. I did go to the gym friday and saturday of the this weekend, and my hands sweat a lot when i work out. My only thought is that the sweat is causing the blisters.
I've researched Hand eczema but i don't think that's what it is. It's never been itchy or painful (the cracked fingers are painful but it only gets bad in the dead of winter) and it gets worse with cold weather instead of warm.
Is this something that can happen from sweating? Could it be from the exercise machines at the gym? Is there anything i can do to stop this from happening? Is this a form of eczema? Should I go to my dr?

Pompholyx(Dyshidrosis)- yes indeed it is to do with sweating. Nickel sensitization or fungus elsewhere on the body can precipitate.Try hand cremes containing glycerine.Do consult your doc.
