But I don't play Tennis?

I have tennis elbow I think. I have had it for a few weeks now and even though its pretty slight, it is starting to annoy me. You would think with all the hammering etc, that would have done it, but no. It was a machete, I was clearing a lot of brush in the garden that I had been putting off for years and I used a small folding saw for the bigger stuff and a machete for clearing and clearing small branches etc. I noticed it a few days after and just thought little of it and thought it would fade in a couple of days. It has stuck around though. I have done some forging, nothing too heavy and seemed to have managed all right. So I will just have to play it by ear but I have a real hammering urge at the moment.
