Brief answer....Your numbness has no relation with gall bladder removal.
Detailed answer....
Hello,
Thanks for the query.
I have read your query and understand your concern.
Very frankly speaking a gall bladder removal has no connection with these symptoms of numbness in both arms and legs.
As far as proper reason for this is concerned, it is very difficult to offer but most likely it could be due to fatigue after the surgery or could be due decreased blood flows to arms and legs because of less movement and spending more time resting on bed or may be due to lack of water and electrolytes.
Drink plenty of water,move around and I hope you shall be all right in another few days.
Nothing to worry as such and just relax. These are just few of the bizarre symptoms which crop up after the surgery but are very temporary. You should be all right in next few days.
I hope it helps,however you are most welcome to revert to me for any further query.
Best of luck
Thanks

Hello,
Not exactly. Had shoulder nerves been involved,you would have had numbness in arm only and not left leg. Numbness in left leg can not  be explained by involvement of shoulder nerves.
I think there is nothing to worry. Involvement of any group of nerves would involve that area only and not the entire body. Just relax and wait and watch.
Thanks
