Button emerged from his car at the end of the Canadian Grand Prix with a splitting headache such was the uncomfortable ride he had experienced, describing it as one of the worst of his life.
The bumpy Circuit Gilles Villeneuve in Montreal had resulted in the car bouncing around to such a hideous extent that neither Button nor team-mate Sergio Perez finished in the top 10, ending McLaren's 64-race record-breaking run in the points.
Time has at least cured the headache, and although Button has made it clear he has no chance of winning Sunday's British Grand Prix, he at least has the thrill of racing again on home soil to spur him on.
"I love racing, I love competing and I love jumping in an F1 car," said Button.
"In Canada it was more the bouncing around at the last race. It was painful, rather than anything else.
"It was not the position I was in. It was the constant that (moving his hand up and down) all the way down the straight.
"At Silverstone that shouldn't be as much of a problem. We've got things that can help that, but especially here.
"Even on Friday (in practice) I'm hoping we're going to have good weather and a full house.
"Jumping in the car and driving on to the circuit in front of a home crowd is a very special feeling.
"It doesn't matter where we finish the grand prix or where we think we're going to finish, the British fans are going to be excited about McLaren driving out on to the circuit on Friday.
"The history the team has, seeing a car in real life is something special. I know how that feels.
"I'm a fan of motorsport just like anyone else, so I'm really looking forward to that moment, and hopefully from then on we have a positive weekend."
McLaren have conducted a permissible straight-line test in Idiada, Spain, this week in a bid to cure their ongoing woes that currently have the team a miserable sixth in the constructors' championship.
With Button already 107 points down on championship leader Sebastian Vettel, and after Canada ruling himself out of the title battle, he naturally has one eye on next season when new engine regulations will completely alter the playing field.
"We all know this year hasn't been easy for us, but I wouldn't say it's been my worst year in Formula One," assessed Button.
"If you look at the results the last race was our worst of the season because we didn't score points.
"In every other race we've realistically had a good chance of scoring good points and getting into Q3 if everything went our way.
"I was fifth and a chance of getting close to a podium in Malaysia; Checo was sixth in Bahrain, so we've had some alright results, but still that's not good enough for McLaren. We should be winning.
"Next year is a completely different challenge for all of us and you do all start from square one, so it will be really interesting to see who does get the jump on everyone.
"I do think it will be one of the bigger teams, like us or Ferrari or Red Bull."
