Hand/Finger Cramps in first trimester

I heard that hand/leg cramps are common in third trimester. What about the first trimester? I'm in my 11th week n it's been hard to sleep on days when I have this cramping or stretching/pulling feeling on my hand and leg (since about week 7). Since yesterday noon, my fingers started cramping n pulling and it's not going away. Wondering if this is normal and if there's any remedy? I applied some ru yi oil on my fingers so heat can slightly mask the cramping feels. Also not sure if it's safe to use ru yi oil cos some of my friends said not to.
