Plaintiff contends the trial judge erred in instructing the jury that there was no evidence that plaintiff sustained a permanent injury or would suffer future pain or incur future medical expenses as a result of the collision. There was no error in this *547instruction. The collision occurred on 6 June 1966. While plaintiff testified at the trial in November 1970 that his back “hurts a little bit all the time, every day,” and “[i]t is paining me right now,” he also testified that since the collision he had seen doctors only on two occasions. On 16 June 1966, ten days after the collision, he was examined by Dr. Everett L. Jeffreys in Winston-Salem. Arrangements for this examination were made by plaintiff’s attorney. Dr. Jeffreys testified that he found plaintiff’s condition normal except that in his opinion plaintiff had a small midline minimal herniation of the nucleus pulposus in the lumbar region in his lower back. Dr. Jeffreys did not testify that this injury would be permanent. Dr. Jeffreys did not again see plaintiff until they both appeared as witnesses at the trial. The only other doctor seen by plaintiff was Dr. Frank Edmund-son, who examined plaintiff on 29 September 1970 at the request of defendant’s attorney. Dr. Edmundson testified that “ [i] nsofar as the herniation of this disc which Dr. Jeffreys testified to, I can say he did not have one at the time I examined him.”
In our opinion the evidence in this case was not sufficient to warrant an instruction permitting an award for permanent injuries or for future pain and suffering or for future medical expenses. “To warrant an instruction permitting an award for permanent injuries, the evidence must show the permanency of the injury and that it proximately resulted from the wrongful act with reasonable certainty. While absolute certainty of the permanency of the injury and that it proximately resulted from the wrongful act need not be shown to support an instruction thereon, no such instruction should be given where the evidence respecting permanency and that it proximately resulted from the wrongful act is purely speculative or conjectural.” Short v. Chapman, 261 N.C. 674, 682, 136 S.E. 2d 40, 46. The opinion in Short v. Chapman, supra, quotes with approval from Diemel v. Weirich, 264 Wis. 265, 58 N.W. 2d 651, as follows:
“ ‘It is a rare personal injury case indeed in which the injured party at time of trial does not claim to have some residual pain from the accident. Not being a medical expert, such witness is incompetent to express an opinion as to how long such pain is going to continue in the future. The members of juries also being laymen should not be permitted to speculate how long, in their opinion, they think such pain *548will continue in the future, and fix damages therefor accordingly.’ ”
Where, as in the present case, the injury complained of was subjective and of such a nature that laymen cannot, with reasonable certainty, know whether the injury is permanent or whether there will be future pain and suffering, it is necessary, in order to warrant an instruction which will authorize a jury to award damages for permanent injury or future pain and suffering, that there be offered evidence by expert witnesses who can testify, either from personal examination or knowledge of the case, or from a hypothetical question based on the facts, that there is reasonable certainty of permanency of the injury or that with reasonable certainty the plaintiff may be expected to experience future pain and suffering. Gillikin v. Burbage, 263 N.C. 317, 139 S.E. 2d 753. In the case before us there was no such evidence. Appellant’s assignments of error directed to the court’s instructions to the jury are without merit.
 After the trial plaintiff moved that the court in its discretion under G.S. 6-21.1 allow attorney fees to his attorney for prosecution of this action. After hearing, this motion was denied, to which ruling appellant now assigns error. The allowance of counsel fees under the authority of G.S. 6-21.1 is, by express language of that statute, in the discretion of the presiding judge. There has been no showing of any abuse of the trial judge’s discretion, and this assignment of error is overruled.
We have examined appellant’s remaining assignments of error and find them without merit. In the trial and judgment appealed from we find
Chief Judge Mallard and Judge Vaughn concur.
