My lower right arm and elbow

IM new here and not no tiger woods I would rate myself as a intermediate beginner. Yesterday I was out playing golf and before we started I was at the driving range with my driver and after a couple hits I felt a sharp pain in my lower right arm elbow area and today my whole lower arm is black and blue swollen. Have no clue what has happened. And very frustrated with my drives, I cant seem to be constant with hitting the ball straight and was wondering if I can get some advice with my driver and clubs and what could have happened to my right arm area.

Thanks,

Well, I'm no doctor but you could have a wide range of issues, including a broken forearm.  See somebody if pain and swelling persist.

Sharp pain followed by swelling and black and blue = bad. Get to an urgent care clinic.

Post a video. There's lots of doctors on this site. Maybe @Ferguson can fix you up.

Could be golfers elbow, i had this from gripping too hard. Gave me pain from just below the elbow joint right down to my hand and middle fingers. Definatley see a doctor as any sort of tendon/ligament damage isnt nice

It looks pretty good. :-P Start a My Swing thread and post some video. No one can really help without actually seeing what your doing in your swing now.

Last year, after playing very little for the previous 2 years, I played 6 out of 7 days straight.  I got a little bit of what felt like tendinitis in my right forearm, so I got one of those velcro wraps to wear.  After the first round wearing the wrap, my whole forearm arm turned black and blue like I'd been worked over with a hammer.  I think it had something to with the wrap, although I know it wasn't too tight because it even slipped down to my wrist on a couple of swings, but I'd never had anything like that bruising before.  Nor has it recurred.  Don't have any idea what really caused it, but it faded in about a week, just like any bruise would, and never really hurt that much, just a sort of dull ache that I didn't even notice unless it thought about it.  The tendinitis gradually healed too after I just quit playing for a couple of weeks to let the arm rest.
