Yes and No. It is called testicular torsion. It is actually the spermatic cord that is twisted and this cuts of the blood supply to the testicle. If not corrected this can cause the testicle to die, then it has to be surgically removed. There are implants available for those who lose a testicle though, but just for looks, it won't be functional like a real testicle. The testicle itself cannot really twist, but the problem is still known as testicular torsion and many people think of it as a twisted testicle.
If you are in pain, or are worried, better to speak to a doctor. But testicles are generally quite resilient, and no harm is usually done. Still, if in pain, or even slightly worried, see a doctor, who should help in a friendly, useful, helpful and professional manner.
You cannot "grow" testicles. But if you are male you should have testicles and they will develop as you grow.
testicles = cōleī
