Pins and needles in arms

I have been trying to research whats happening and I dont believe its pregnancy related carpal tunnel syndrome. But Ive been having a hard time sleeping at night because my arms fall asleep and its very painful. At first I could only sleep on my back to make sure it didnt happen, now its happening when I sleep on my sides and back and stomach/sideish..... Even while sitting it happens and I only seem to be ok while standing.... is there any thing I can try or do to help make it stop? Ive tried a million pillows placed everywhere, wrists splints just in case but nothing seems to be working...
