I've been waking up to swollen hands lately and sometimes the pain is so bad it actually wakes me up and I start to cry cause the pain is sooo bad. After a while it'll go away and I could actually feel when it starts to go away. Usually it takes a half hour or so. Then lately it has become more frequent and often that I have begun to tolerate the pain. whenever I'm holding something in my hands for more than 30 seconds the tingling and pain will start up and I'll have to put down whatever it is I am holding. What can that be?
