What Is That Lump On Top of Your Foot?

What can cause a lump or bump to appear suddenly on the top of your foot?

Did you wake up one day and notice a small bump on your foot that has gotten bigger since you first noticed it? Maybe it’s painful, maybe not…but more importantly, what the heck is it?! If you’ve suddenly noticed a lump or bump on top of your foot, you may have a ganglion cyst. A what? A ganglion cyst is a fluid-filled lump that can occur anywhere on the body. Ganglion cysts can commonly occur on the foot, especially along the top of the foot or on the toes. Very rarely can they occur on the bottom of the foot. This type of cyst is usually soft to semi-firm and you can feel it move slightly when you push on it. Depending on where the cyst develops, it can be painful. Cysts that occur on top of the foot can press on a nerve which can cause tingling or burning sensation if the cyst gets too large. Most people with a ganglionic cyst on top of their foot complain of pain when their shoe presses on the area. Ganglion cysts can be tricky to treat. At Advanced Podiatry, we take xrays and use an ultrasound to evaluate the cause of the cyst as well as the size. Treatment can usually be performed in the office to alleviate pain associated with a ganglion cyst. Conservative treatment usually consists of cortisone injection to reduce inflammation around the lesion and padding the area to reduce pain in shoes. Minimally invasive procedures that can be performed in the office include aspirating the fluid or draining it from the area. Depending on the size of the cyst, larger ganglionic cysts may need to be surgically excised to relieve pressure from other soft tissue structures such as nerves or tendons.
