What causes sharp pain in shoulder blade and hip when coughing?

Multiple Pains: Pain can be caused from a variety of reasons ranging from arthritis to multiple myeloma. An internet answer can not replace a physician evaluation, history and prognosis but one must consider that an arthritic process can cause multiple joint pains during a flu infection. Other medical problems need to be excluded therefore a trip to your personal physician is needed.

Multiple answers: Sharp pain in the shoulder with coughing could represent a problem with a cervical or thoracic disc problem or possibly an issue with tendonitis in the shoulder. Less likely but possible. Definitely needs to be evaluated.
