For weeks, Mirza Teletovic knew something was wrong. He just couldn’t figure out what.

So when Teletovic found out in January he was suffering from blood clots in his lungs, while upset he would miss the remainder of the season, he was happy he knew what the problem was.

“I didn’t feel right,” Teletovic said. “My calf was hurting for no reason. … I couldn’t run. I would go up and down twice and have to get my breath together.

“I would come home and people would wonder what’s wrong with me. My family, everybody realized I would just lay down and sleep because I was tired all the time. I couldn’t get it together.

“So kind of when I went to the hospital, it’s tough to find out. It’s definitely serious you have a blood clot. But I felt relief because I knew what was wrong with me. Especially when doctors told me it was treatable. It happens every day, we have medications for it, you should be OK.”

Teletovic said he’s already back working out fully, with the only restriction on him being to stay out of contact drills because of the blood thinning medication he’s on. He said he should be able to return to full basketball activities in July.

The 6-foot-8 power forward, who is a restricted free agent this summer, made an impassioned pitch to return to the Nets next season, saying he loves everything about the franchise.

“They were my first choice coming to the NBA,” Teletovic said. “I love the team, have a lot of respect for people who work for the Nets and the organization. … I really enjoyed it, so I hope I stay.”

He also had a message for Chris Bosh, who also was lost for the season after being diagnosed with blood clots a couple weeks ago.

“I want to take this opportunity to reach out to Chris Bosh and tell him he doesn’t have to worry,” Teletovic said. “He’s going to be good, and he’s going to start working out soon.”
