Chemotherapy Effects on the Feet

Cancer is a difficult thing to deal with.  Once you are diagnosed, there are so many decisions to make regarding your treatment options.  And if chemotherapy is in your treatment plan, your oncologist will describe the side effects and complications as well as the benefits.  But so often, you don't hear about what happens to the feet and legs from chemotherapy treatments.  What you will read below does not affect everyone undergoing chemo, but will help you understand what's happening if it does.

1.  Tinea pedis or athlete's foot
A couple of my patients have described this as "wicked athlete's foot".  It often presents as multiple small red blisters that can be filled with a clear fluid and itches like mad.  As your immune system is lowered by the therapy, your ability to fight off fungal infections is reduced. This type of blistering athlete's foot can also be very painful.  And the open areas can become infected. The best option is to use an antifungal gel instead of cream to dry the areas and kill the fungus.  We will attempt topical therapy unless the infection is so bad that pills are necessary.  Often a short course of oral antifungals is all it takes, usually less than 2 weeks.

2.  Paronychia or infection around the toenails
The skin around our toenails is full of bacteria which naturally occur on the skin.  In a patient with a lowered immune system, this bacteria can overgrow and cause redness and swelling around the nail borders and cuticle area.  The more swollen the skin gets the more likely an ingrown nail can occur.  Wash your feet and toes daily with soap and water and don't forget to get between your toes.  If you are noticing redness around the nails, topical and oral antibiotics are your best option preventing serious infections.

3.  Nail discoloration and loss
Increased stress on the body can often be seen on our toenails, just like the rings on a tree.  After significant events like major surgery and chemotherapy, the nails can become brittle, yellow, crumbly and actually just fall off.  Sometimes the color of the nails can be quite intense like blue or purple or red.  Don't worry to much if your nails change or fall off.  Often within 1-2 years after you have finished your treatments, the nails regrow.  But beware, they may look a little funny.

4. Edema
Excess swelling of the legs (and arms) can occur with cancer treatments and should be addressed by your oncologist as soon as it is discovered.The more swelling you have the more painful your extremity can be, thus making you feel worse than you already do. Oral medications can help with the swelling as well as compression garments.   It is very important to bring this swelling to your doctors attention as it could be caused from a DVT, deep vein thrombosis, or clot in your leg.  These can be serious and need immediate attention.

5.  Ulcers
Increased pressure to the heels from sitting or laying in one position too long can cause a sore or ulcer. Certain cancer treatments like radiation can also cause sores. And if you are diabetic or have neuropathy or poor circulation, you are at high risk of ulceration. While undergoing any type of treatment for cancer, if you develop a sore on your skin, it needs to be addressed right away.  This can become infected quickly and just putting neosporin or vaseline on it isn't going to help. Wound care from a wound care specialist is your best option at preventing severe infections and complications.  The team at FAANT are experts in lower extremity wound care.

Flip Floppin' Away to Flip Flop Injuries

Trust me! I can absolutely relate to the thoughts of so many who have waited an entire winter, (which thank goodness is not a long one in Texas!), to finally let their feet “breathe”! And what better way to do this than in a flip flop?? Even the bottom of the foot gets some air as the flip flop flips up!

As you may have already suspected, podiatrists do not love the flip flop. And as much as you may love them, deep down you know they are anything but stable, and not the best contraption to protect your feet. I wanted to give you a "leg up" on the flip flop injuries we see on an almost daily basis in case you were considering spending your days of summer in them!

You may be surprised how many injuries are as a result of the flip flop. The most common injuries to look out for are turf toe/bruising, nail injury, tendonitis from prolonged wear, heel pain, arch pain, ankle pain/sprains, and fractured toes!

Now, believe it or not, and I know it sounds inconceivable that a podiatrist could actually recommend wearing them, but I actually do recommend using a flip flop around pools and locker rooms, where athlete's foot and warts thrive! In fact, I feel strongly that in these circumstances, you should wear these (or a water shoe) for a barrier of protection! I also like the idea of wearing a flip flop at home to avoid walking around barefoot! Look for flip flops with little to no wedge in these areas and one with an arch. Now, flip flops at Disney World or sight seeing in Europe or on a long day of shopping?  Think again!

Could we possibly keep you out of a flip flop? For the die-hards, it is unlikely that we can keep you out of them!!

Ahhh, but we have just the thing for you, around the corner here at Healthy Steps! Step through our lobby door and you will find Healthy Steps carries the cutest, most stylish flip flops with, yes indeed, WITH an arch that really can provide some support!

Maybe while you are there you will also notice the arch sandals with straps around the ankles that are just as stylish and a lot more supportive! Happy Shopping!
