Full western forehand...2 handed backhand, but stick more with my 1h slice backhand. I'm certain the pain is being derived from my forehand side and not serve, backhand, etc. I mostly get the pain on 'awkward' forehands...
I swing mostly flexible racquets (PST Ltd and 4D 200 mostly), but I used full poly (Cyclone 17 at 52lb).
Now, I have pain even taking practice swings. The pain isn't HORRIBLE (maybe a 6 out of 10), but it's definitely enough.
