Prozac (fluoxetine): If recently started, dose adjusted, or taken late at night, very possible minor effect. Consult your doctor.

Anxiety & numbness: Let your doctor know. Is the Prozac a new medication or have you been on it for a while. Chances are low that it is caused by Prozac. See: https://www.drugs.com/sfx/fluoxetine-side-effects.html
