I have had it for the last 4 months or so and have been to chiropractors,otespaths the lot and have done the right thing and gone back to the GP,i have had golfers elbow but it isn`t bad enough to stop me from working.Funny enough it dosen`t bother me much at work it`s usually when i stop or at night,the best thing you can do is catch it early and makesure you wear an elbow strap when at work it really helps and if put in the right place will drastically reduce the pain and symptoms you have,golfers and tennis elbow runs a course and it`s normally about 9-10 months.Phisio is the best thing for it and if you go to the doctors you will get it free for about 5 sessions,if you`ve got that numb feeling in your hands in could be that your ulner nerve is catching on the bone inside the elbow and this can be due to WFPoleing,don`t do what i did and panic get a strap and go to the doctors he will put your mind at rest.When your WFPoleing makesure your palm is faceing your body this also reduces the strain put on the muscles your agrovating,hope this helps you.
