The Welshman came off the bench during his side's 3-0 defeat at Everton on Sunday after spending three months out with a thigh problem.
Despite seeing the Gunners lose at Goodison Park, Ramsey is happy to be back among the action following a lengthy layoff.
"It was very frustrating for me to be out for three months of the season when things were looking so good," the 23-year-old told the club's official website.
"These things happen in football and I am just glad to be back out there now. Hopefully I can show what I can do, help this team achieve Champions League football again and hopefully have a medal at the end of the year."
Arsenal return to action on Saturday when they go up against holders Wigan Athletic in the FA Cup semi-finals.
