I have a golf ball in my right quad since Monday! its from POG gear after he switched to Mig oil also. How long usually for that to go away?
1200-1800mgs ibuprofen daily for a week to reduce swelling and rotate between hot and cold on area. Best is to have a hot ass bath for a good 30 minutes and massage the area during bath and after with lotion and then apply a cold pack. Do this daily and should go away soon. I've had a lump in my ass that took a solid month to go away and that was from some garbage test from Euroking many moons ago.
My advice dude......brew your own and in GSO for now on
