Suffering Tendinosis

I had a tendinitis last year, i never stopped playing sports and lifting, so it became a tendinosis, i started treating it this year in march. Has anybody sufferd from tendinosis? How long it took fullt heal? I have been without sports since march, and my knee still hurtts a bit, i just want to get back to sports, and lifting weights, and i haven’t been feeling very good emotionally lately cause the pain seems not to go away, i just want ruun, sprint, squat!!

Thanks, any recommendation, experience, advice please
