Taking Creatine while Tendonitis?

hello peeps, baseball season almost here and I'm ready to start throwing to warming up the shoulder. For the past few years Ive had tendinitis on my right shoulder, so much pain I couldn't play one whole season. This year I'm in good conditions, Ive been working out the muscles around my shoulder and they are in excellent condition. Since I have about 6 weeks left, I thought of taking creatine as a supplement. Is it a good idea? please dont teach me anything about Creatine, I know what I take into my body. Im just asking if its a smart decision if I take creatine for the last 6 weeks as a supplement, even though I have tendonitis. So good or bad?
