Yes, but this sounds like it has a lot to do with arthritis
I have suffered with what is known as LL potassium, Lethal Levels, I measure 2.9 one time, I was itchy all the time, and that has something to do with pain. Any lower than that, I could have been in deep trouble, as at that point other things happen to the body, that are more serous. I strongly suggest that you talk to your doctor about this and have some more blood work done, just to be safe. Hope this helps, good luck to you.
