I was camping and stepped on something last weekend, I noticed pain all week but not to bad and I though it was bad athletes foot. But yester I looked and noticed what looked like a sliver but it ha calist over already. I tried taking it out today, but nothing was there, I dug out the area looking for it but now there s just a small whole and a red Line going up my foot. My foot is now tender on the top where the red line is going.
Looks kind your leg is inflamed and need some antibiotic with anti-inflammatory as well painkiller treatment.  If there is a wound then do proper Chat Doctor.  And yes do not move out much and keep your leg in elevated position at home to reduce swelling and take rest.  It should be fine in two or three days.  For medication and
