Dwyane Wade and Chris Bosh have been through both good and bad times over the past five years, which has helped them grow closer.

Bosh turned 31 on Tuesday, which prompted Wade to post a heartfelt Instagram message to his teammate and friend. The message shows just how much Wade cares about their relationship.

While Wade and the Miami Heat are battling to make the playoffs, Bosh is out for the season after developing blood clots on at least one of his lungs. As Bosh deals with his health issue, Wade is behind him and supporting him all the way.

On his own Instagram account, Bosh celebrated his birthday with a throwback picture:
