Why am I Having Itchy/Burning Fingers?

Why is that when I put a lot of strenght into my fingers they kinda get stuck?

• I saw my brother cracking his knuckles when I was 3 years and was like "WOW like the movie villians. Teach me!". He said "Only real men can crack their knuckles" ^^ So I kept trying and it eventually cracked a few minutes later... After that I couldn't get them to crack again till I was 10 years old wich is where I got addicted to it. Ever since then I frequently crack my knuckles, finger joints, wrists, neck and back. Mostly my fingers and knuckles though. I'm 21 now and since of two and a half years when I tightly take hold onto something, let's say a bag that weighs 25kg (the garbage bags at my work weigh about that amount when full) and I will hold onto it with one hand for 30 seconds and let go, my fingers get sore and stiff (like stuck in place) and I have to really straighten my fingers to get them loosend up again... Does this have anything to do with me cracking my fingers for over 10 years? My uncle warned me back then but it was already a habit. Not that I'm planning on stopping with it now, I'm just curious. I read this article about a man doing it for 50 years and having no side effects. So that's why I'm asking =)

• Answer:

  No cracking, snapping fingers and knuckles do Absolutely no damage at all.. read this I just posted on another question.. In fact, it's not dangerous at all, said Dr. Jonathan Kay, clinical director of the rheumatology unit at Massachusetts General Hospital. "The cracking sound you hear when you pull on your fingers is caused by the release of negative pressure within the joint," he said. Technically, this is called cavitation. Inside every joint in the body, a gooey substance called synovial fluid coats the surfaces of cartilage to protect them. Just as two discs coated with mineral oil stick together and can only be pulled apart with a bit of force, so it is inside the joint. When you pull, you break the vacuum seal created by the synovial fluid and the breaking of that seal causes the popping sound, from the bursting of bubbles of gases dissolved in the fluid. It takes about 20 minutes for the seal to re-establish itself. So crack your knuckles all you want. You might stretch a few ligaments, but you will not give yourself arthritis. But it'll be no fun unless you wait 20 minutes between cracks. Now with your fingers becoming "stuck" I also have that problem and I have Lupus.. and osteoarthritis.. so you should really talk to your doctor about that and ask him to have you go for blood tests to rule out other diseases.. Good luck ;)
