I was suffering from restrictive movement in my shoulder with pain when moved in certain directions. Butterfly was the biggest problem area for me as that movement of lifting my hand straight up was resulting in intense shoulder pain.
Gal identified weaknesses in my shoulder brought on by two things. One, as a swimmer we tend to favour certain muscles, they dominate our shoulder weakening the less used muscles. The second area was an old long forgotten injury from my teen years where I ripped my deltoid.
The Shockwave therapy worked on the old injury and Gal's physio and exercises worked on the weak muscles. After the first session I felt the difference, by the end of five sessions I was well on my way to recover, swimming butterfly again without pain.
