DRUMMER CAFE

I've been playing alot lately, just on my little pad between studying for Uni, 'cause study is getting super turbo so naturally, so is the drumming to relieve the stress. Problem I just noticed is that on my right hand the first knuckle of my first finger (where the stick generally sits for my french grip styles) is feeling a bit achy, like inflammation or something.

I've never had this there before so I was just wondering if anyone else had this and if so what was it and how did you fit it?

I've got a feeling I'm either gripping to hard (which seems a bit wrong to me) or it's just the damage building up from the stick shock.
