A member asked:

Fell into a very cold lake for about a minute earlier today. my hands are now feelings a little "heavy"/tingly.could this be related to the accident?

A doctor has provided 1 answer

Yes: You are probably experiencing a localized histamine release and changes in blood vessel permeability, the itching is next. This process will be short lived. If it continues, or spreads and is persistent several hours later, care should be sought as this could be related to another cause that may require direct attention.
