The Real Madrid star returned to action in Saturday's 2-0 win over Malaga and insists he has now recovered from a thigh complaint that affected his preseason.
Bale came on as a second-half substitute and won the penalty that Cristiano Ronaldo converted to seal a 2-0 win for the hosts at Estadio Santiago Bernabeu on Saturday.
Reports in the Spanish media this month had claimed Bale was suffering from a major back problem - rumors which were promptly dismissed by the club - and the Wales international has now stressed he has no concerns over his long-term fitness.
"It's been greatly exaggerated about my injury," Bale told AS. "I'm over the injury I suffered. I had a small thigh issue and as a result I've not had a lot of playing time. I missed preseason and could not run or train without discomfort.
"The truth is that it was not important. Everything is exaggerated enough. I'm already playing again. Winning was very important for us today and I think we played well throughout the match.
"We deserved the win and now I'm looking forward to facing the next two games."
Madrid still sits third in La Liga after the win with 22 points from nine games, but has closed the gap from Barcelona at the top to just three points ahead of next week's Clasico at Camp Nou.
