After working 8-10 hour day at a local supermarket stocking, pulling loaded pallets off a truck, lifting cases of products, a red swollen lump (size of a lemon) will appear on the front my on my shin. (The lump is tender to touch and sometimes will appear on both shins. Today the lump/ knot is only on the left shin) I wear compression socks most work days and to treat the swelling, inflation & pain, I use ice packs and take anti-inflammatory medication. I 5 10 tall and weigh 168 lbs
