Hi Marty10,
NSAIDs and injections...
...well, if there are signs of inflammation, treat them - heat, swelling, pain, redness, loss of function...
As for injections, i am fairly confident there is research that suggests a short term benefit in terms of pain but longer term results in the same group leading to decreased improvement overall.
If you were treating someone who strained their elbow on the weekend, you are probably looking at some form of inflammation. If you are treating someone with a 6 month history of elbow pain, you are probably treating something that is not inflammation.
In the end, we are trying to break a cycle and gradually expose the injury to load to assist in repair - i am fairly pragmatic about such things...especially having suffered from LE myself...i only ask that the patients know about WHY they are getting a treatment etc.
Cheers
