Pictures quality is very poor basic knowledge is covered in this book but i want more about cupping benefits in musculoskeletal and neurological pain, should be systematic content eg. Cupping in Cervical radiculopathy , lumber radiculopathy, adhesive capsulitis , osteoarthritis Rheumatoid arthritis...etc I'm not satisfied with the content in it.... Please add more topic related to cupping practice... And use colour pictures to better demonstrate... Allah Hafiz
