Nothing I can think of. I still type but not an unusual amount. Have also had a lot of head tingling and pain throughout my scalp as well as some minor discomfort in my teeth and tongue. It is probably the PN just making its rotation throughout my body. The funny thing is that when one thing hurts, the other feels better (for example my feet haven't been as bad as in the past). The hand cramping thing however has definitely caught me off guard.
