tennis arm...!? テニス筋痛！？

I played tennis with my dad for a few hours and
this is the result.....
親父とテニスした結果こんな事に・・・

I used to play tennis in highschool and college,
but recent years I only play once a year in Japan...
I guess it was too much for my forearm muscle. lol !!
I had to do some "okyu" which is a packed herb weed
which you light it up to create a focused heat onto
the sore muscle areas.
昔は高校、大学とテニス部で毎日練習してたけど、
今はほぼ一年に一度日本でやる程度・・・。
なので１日やっただけでこのザマ！！
お灸三昧！！！（←ジジイか～？！）
