I have burning numbness in tongue after wisdom teeth extraction., what do you recommend?

Keep area clean. At this point, there is nothing to worry but to wait for it to heal. Keep the area clean to prevent bacterial superinfection. Most of the time, the numbness will significantly reduced and go away over time. Just wait patiently. You must trust your doctor since he/she is trying his/her best for you. Time frame may be six month to a year...
