Can Planche training cause winging scapula?

Hello, this summer I not trained a lot but stretched and relaxed instead because I found out I have scapular winging. I watched a lot of videos to inform myself but can't really find a way why my shoulders hurt a bit and my rhomboids always feel tight. Is it because of Planche training, I recognized instantly that I clearly don't have enough shoulder mobility because when I tried to elevate my arms the scapula came up, but my main problem I think is the rhomboids and every time I breathe heavy my spine crackles around the upper back area (it feels good tho).

Hi Horváth, I think that the causes of the problem could be multiple factors, in this case, visit a physio it is the primary solution.
