Tongue tie issue after surgery. Norma!

Hello lI'm 22 years old male. I had tongue tie surgery 2 days ago in Aims delhi( dental department) through laser and i also have 7 stitches.I haven't been recommended to do any exercise after the surgery & also asked to do not speak for 2 days. but at the google it is showing exercises are necessary or it will reattach again. I'm tensed if it will reattach again if I don't do the exercise. I talked to my Doctor today and she said don't do any exercise and don't talk. Pls help me l'm very tensed, do i need to do exercise to prevent it from reattaching or not Also I'm not able to speak fluently after my surgery, nd it's been 2 days. Also I'm not able to lift my tongue & stick it out of my lip even after the surgery. Why is it happening, it should come out & lift completely now. Also I'm having a numbness at the tip of the tongue. I have seen at you YouTube people lifting their tongue completely, but I'm not. Is this a failure of my surgery or anything isue with the surgery or it's norma
