I have avulsed fracture of humerus (at the top), in sling, pain worsening?

See doc: If u have sustained a recent fracture of the greater tuberosity of the humerus( assuming from history ) that is not significantly displaced(>.5-1cm)non- surgical treatment is generally sling and swathe . Sometimes the pain may worsen the first week. Try icing the shoulder and sleeping in a recliner position or actual recliner.U may require pain medicine. After 2 -3 wks.Pain improves dramatically.
