I Keep Getting Muscle Cramps I Was Told This May

I keep getting muscle cramps i was told this may be due to low potassium i do sweat a lot (hot flashes) so i try to drink a lot of water i do take potassium pills sometimes, but i still get them could this be from something else. To me its more like muscle spasms and they are not centralized but mainly in my top torso like stomach, back my left hand has started to even freeze up on me.
