In August 2010, as a result of testing positive for use of doping, Rahm was suspended from all professional ice hockey in the 2010–11 season as well as 2011–12.
Rahm started his senior-level career playing for his youth team Sunne IK in Sweden's third-tier league Division 1.
During the 2006–07 season, Rahm played in 28 games and improved his save percentage to .921, again ranked second in Division 1 E, but Sunne's sixth-place finish did not qualify them for an Allettan spot and they moved on to play in the spring series where Rahm posted an impressive .942 save percentage with two shutouts in five games.
During that season, Rahm was briefly loaned to Södertälje SK in HockeyAllsvenskan where he dressed as a backup for two games,[2] and to Frölunda HC in Elitserien where he joined as an extra goaltender during practices.
[7] After the suspension, Rahm signed a two-year contract with reigning champions Brynäs IF of the Elitserien (SEL) on July 5, 2012 to return to the Swedish top-tier league for the 2012–13 season.
