My hands do that sometimes. It is very frustrating when they act up when I am playing my guitar. My right hand will do the claw thing and make it where I can't finger pick. Sometimes I can't chord properly. Other times I do just fine. I never trust my hands alone to carry my instrument. If I carry it myself, I always use the strap. Usually my husband sets up my stuff and puts the guitar in my hands. I am so afraid that I will drop it.
