I was clearing some brush from property and when I was piling it up a thorn poked me in top of wrist, right into my blood vein. Blood squirted every where and it made the vein bulge up. I had cold drink in my hand so I kept working n placed can on the spot as much as I could. But the vein went down but still swelled some and its getting stiff and hurts pretty good. Soaked it in Epsom salts n it makes it stop hurting and I can move it around, but after about 5min its starts hurting again n is stiff all over again. I'm pretty sure it was a mesquite thorn. There was several limbs in there I had removed...what should I do?
