Gall bladder surgery
has no relation to numbness
If the Intravenous cannula
was kept in the hands,then it may be the cause for numbness as minor nerve injury
might have occured.
Otherwise it could be just minor complaint which might have occured due to pressure effect.
Please give her B complex tablet with minerals and antioxidants.
I don't think she will be asked for tests.
Nothing to worry
Wish her good health
