Smith-Blair, Inc. v. Jones, 77 Ark.App. 273, 72 S.W.3d 560 (2002); Matthews v. Jefferson Hosp. Assoc., 341 Ark. 5, 14 S.W.3d 482 (2000). |nMoreover, the Commission’s decision was based on Dr. Young’s statement that he felt it appropriate to see Wilson in the future if Wilson continued to have pain that interfered with his daily activities. See Patchell, 86 Ark.App. 230, 184 S.W.3d 31 (<HOLDING>). Accordingly, we affirm on this issue as well.
