¶1By the testimony of Dr. Richard Adams, plaintiff attempted to establish that the blow received in the accident caused phlebitis in the plaintiff’s right leg, which led to the development of varicose veins in that same leg. It was stipulated that Dr. Adams was a licensed practicing physician and a medical expert, specializing in the field of orthopedic surgery. Dr. Adams testified regarding his experience with varicose veins and phlebitis, and his background in dealing with vascular diseases and surgery of the vessels.
¶2Plaintiff asked Dr. Adams a hypothetical question to establish the causal connection between the trauma of the accident and development of varicose veins in the plaintiff’s leg. Plaintiff asked a hypothetical question, because Dr. Adams had not examined the patient for varicose veins or phlebitis and there*339fore did not have personal knowledge of the plaintiff’s condition. The trial court refused to allow the witness to answer the hypothetical question, because the doctor’s testimony would be “speculative.” The doctor’s opinion would have been that the plaintiff’s phlebitis could have caused the varicose veins.
¶3We do not necessarily agree that the doctor’s opinion should be excluded because it is “speculative.” See Lockwood v. McCaskill, 262 N.C. 663, 138 S.E. 2d 541 (1964). However, we find no error in the ruling not to allow the answer.
¶4The record discloses no evidence having been admitted prior to the hypothetical question concerning plaintiff’s varicose veins. Thus the question contains facts which are not in evidence and which cannot be inferred from the evidence.
¶5A well recognized rule in North Carolina requires that a competent hypothetical question include only such facts as are in evidence or such as may justifiably be inferred. Bryant v. Russell, 266 N.C. 629, 146 S.E. 2d 813 (1966) ; Crutcher v. Noe, 17 N.C. App. 540, 195 S.E. 2d 66 (1973) ; Stansbury, North Carolina Evidence, Brandis Revision, § 137 (1973).
¶6Plaintiff also assigns as error the court’s refusal to allow her testimony concerning expenses for, and treatment by, a doctor in Ohio. We find no error in the court’s rulings. There is no evidence to show the necessity for plaintiff’s treatment in Ohio (where she lived for awhile after the accident in North Carolina). Furthermore, there is no evidence that the medical expenses paid in Ohio were reasonable in amount. Ward v. Wentz, 20 N.C. App. 229, 201 S.E. 2d 194 (1973).
¶7We have reviewed plaintiff’s assignment of error as to the judge’s charge as well as her other assignments of error. We find no error in the trial.
¶8No error.
