Corticosteroid injection may be effective in the short term however are of little benefit after a year, compared to a wait-and-see approach. A randomized control trial comparing the effect of corticosteroid injection, physiotherapy, or a combination of corticosteroid injection and physiotherapy found that patients treated with corticosteroid injection versus placebo had lower complete recovery or improvement at 1 year (Relative risk 0.86). Patients that received corticosteroid injection also had a higher recurrence rate at 1 year versus placebo (54% versus 12%, relative risk 0.23). Complications from repeated steroid injections include skin problems such as hypopigmentation and fat atrophy leading to indentation of the skin around the injection site. Steroid injections against appear to be more effective than shock wave therapy. Botulinum toxin type A to paralyze the forearm extensor muscles in those with chronic tennis elbow that has not improved with conservative measures may be viable. Surgery
Surgery is an option. Surgical methods include:
Lengthening, release, debridement, or repair of the origin of the extrinsic extensor muscles of the hand at the lateral epicondyleSurgical techniques for lateral epicondylitis can be done by open surgery, percutaneous surgery or arthroscopic surgery, with no high-quality evidence that any particular type is better or worse than another. Side effects include infection, damage to nerves and inability to straighten the arm. A review of the evidence related to surgery found that published studies were of low quality and did not show that surgery was any more effective than other treatments.
Fitz-Hugh–Curtis syndrome is a rare complication of pelvic inflammatory disease (PID) involving liver capsule inflammation leading to the creation of adhesions. The condition is named after the two physicians, Thomas Fitz-Hugh, Jr and Arthur Hale Curtis who first reported this condition in 1934 and 1930 respectively. Signs and symptoms
The major symptom and signs include an acute onset of right upper quadrant (RUQ) abdominal pain aggravated by breathing, coughing or laughing, which may be referred to the right shoulder. There is usually also tenderness on palpation of the right upper abdomen and tenderness to percussion of the lower ribs which protect the liver. Surprisingly there is often no or only minimal pelvic pain, vaginal discharge or cervical motion tenderness, which may lead to the diagnosis being missed. This may be due to infectious bacteria bypassing pelvic structures on the way to the liver capsule. Pathophysiology
Fitz-Hugh–Curtis syndrome occurs almost exclusively in women. It is usually caused by Chlamydia trachomatis (Chlamydia) or Neisseria gonorrhoeae (Gonorrhea) though other bacteria such as Bacteroides, Gardnerella, E. coli and Streptococcus have also been found to cause Fitz-Hugh-Curtis syndrome on occasion. These bacterial pathogens  cause a thinning of cervical mucus and allow bacteria from the vagina into the uterus and fallopian tubes, causing infection and inflammation. Occasionally, this inflammation can cause scar tissue to form on Glissons capsule, a thin layer of connective tissue surrounding the liver. (Bailey&Love)

Diagnosis
Abdominal ultrasound will typically be normal.
