Hello I am a nurse that at this time is in a remote environment (no access to emergency health care) in the Bering sea. I have a crew member that is complaining of numbness "heavy" Left lower leg. He reports there is no pain associated with this numbness. He also reports that he had knee pain and was wearing a brace that resolved this pain. He has discontinued this brace for the last 2 days but this numbness has not improved. It is also important to note that this gentleman works in a fish processing factory 16 hours per day (on his feet)
