Numbness or tingling in the hands occurs when nerves in the arm or wrist are compressed or damaged, according to WebMD. One of the simplest causes for nerve compression during sleep is when the arm is bent for a prolonged time or rested underneath another part of the body.
See MD: Hand numbness likely is due to pressure on the nerve either from damage, inflammation or direct pressure. Throat sensation can be topical in nature - not likely lemon water, but excess acid could irritate it. This may also be nerve related. So, get to the MD and find out what is going on.
