Hey Tim,
I see that elbow finally did you in. I actually had more issues when I shot a recurve but I guess thats just me.
Anyway, the thing with epicondylitis(which is a true inflammation issue) is that you MUST decrease that inflammation. This is done with meds, ice, injection or whatever. ONCE the inflammation is decreased you can proceed with your activity. PROPER stretching is key here at this point.
If there is a partial tear of the tendon, that will heal on its own IF you allow it. This is where you must really be careful because that partial tear can become fully torn or avulsed from the bone and this will NOT heal and have to be repaired.
I am an advocate of injections if not abused. I have had many myself and if left to heal can work great. I would rather have the medication injected right to the site that you know is invlolved instead of injesting a medication that must go through your system and cause GOD knows what.
Finally, yes over doing it is the worst thing you can do( I know this from experience) and SHOULD know better. I think I ahve finally learned that. Good luck and God bless my friend.
