If the elbow pain is on the side of the elbow closest to the body, it is "golfer's elbow" (medial epicondylitis). If the pain is on the side of the elbow away from the body, it is "tennis elbow" (lateral epicondylitis).
If have medial epicondylitis of the elbow and find that wet heat (aka hottish shower) on the affected area helps (better than the dry heat of a heating pad).
I used to use Arcoxia, but now, if needed, I use Atulox, which is exactly the same as Arcoxia, but half the price: both products are Etoricoxib. I buy Atulox at the Pattaya pharmacies with the distinctive orange colour. (not sure I'm allowed to name the pharmacy chain) My orthopedist advises to use no longer than 5 days in a row, one tablet per day. Available dosages are 60, 90. and 120 mg.
Be sure to read Sheryl's cautions in her above posts: If you use Etoricoxib, use with caution. I second Sheryl's advice regarding the use of Ibuprofen as well. Note, however, that ibuprofen and etoricoxib should NOT be taken together; use one or the other!
My situation is more chronic; I don't expect to ever be completely pain-free, but lowering the pain works for me!
