Tendinitis:  It is a painful inflammation of the tendons and of tendon muscle attachments to bone, usually in the hip, achilles tendon, hamstring and the shoulder rotator cuff.
  Tendinitis results from trauma, hypermobililty, postural misalignment, abnormal body development, and other musculoskeletal disorders.

  X-rays may show; calcium deposits,  bony fragments, and or osteophyte sclerosis (  osteophyte : a bony excrescence or outgrowth ) (sclerosis: hardening )
  Arthrography (radiography of a joint after injection of opaque contrast material ) may be done to see if it shows any irregularities on the under surface of the tendon.
 

  Restricted shoulder movement, especially abduction
  swelling
  Localized pain. The pain may intensified rather than get relief from applying heat to area.
  Pain increasing more so at night
  Calcific tendinitis includes proximal weakness and possibly acute calcific bursitis.( Bursitis is a painful inflammation of one or more of the bursae, ( Bursa: a fluid filled sac or sacllike cavity situated in places in tissues where friction would otherwise occur)
 

  Your doctor may prescribe medication to relieve pain

  Oral anti-inflammatory agents

  Ultrasound

  Application of cold and heat

  Local injection of an anesthetic and corticosteroids to reduce inflammation

  For immediate pain relief, your doctor may give a mixture of a corticosteroid and an anesthetic, such as lidocaine injection
  For extended release your doctor may give an injections of a corticosteroid, such as triamcinolone or prednisolone (it offers longer pain  relief

  Rest and immobilization with a sling, splint or cast to affected area.

  Short term analgesics may be prescribed until the patient is able to perform ROM easily

  Supplementary treatment includes:  fluid removal by aspiration, physical therapy to preserve motion and to prevent frozen 
joints, heat therapy for calcific tendinitis and ice packs.

  May need  to change life style to prevent recurring joint irritation

  * If taking anti-inflammatory medications, take with milk to minimize GI distress.
  Call your doctor immediately if experiencing signs of distress.
