Posted on Thu, 24 Aug 2017
Question: I am a 65 year old female. I have dry, peeling feet and what appears to be a rash on the inside of both feet where my shoes ub.. I also have what appears to be a bunion on my right foot and circular sore on my right ankle bone that is very dry, red, itchy and sometimes sore, It has a brown ring around it. Looks like it might be ringworm. My feet feel slightly numb on the bottom. The condition has persisted for several months. Do you think the symptoms of numbness are from dry skin or something else. What do you recommend.
I do not have a history of diabetes and have good balance. I exercise regularly.
Thanks, XXXXXXX

Brief Answer:
Athlete's foot most probably

Detailed Answer:
Hello,
Thank you for trusting HealthcareMagic for your health concern,

Dry, scaly, peeling and itchy skin of the feet is likely to be due to Athlete's foot. Athlete's foot is caused by fungal infection

You can follow the below measures to treat athletes foot
-Keep your feet always clean and dry
-Do not try peeling the skin as it can injure healthy skin
-Apply Lotrimin anti fungal ointment
-Wear sandals instead of shoes to prevent sweating.
-Keep your feet moisturized. Apply moisturizing lotion.

If you do not notice any improvement in 7 days, I'd suggest to follow up with your primary care provider to look for an alternate diagnosis like eczema, psoriasis.

The numbness you are describing is unlikely to be due to skin problems. Numbness affecting feet is likely due to peripheral neuropathy. Nerve conduction studies can confirm the diagnosis. Since you are not diabetic, other possible causes of peripheral neuropathy like vitamin B12 deficiency, demyelinating disorders need to be looking for.

I would like to know further regarding the circular sore on the ankle. Please describe whether the sore is rash or an ulcer. If possible, attaching a picture of the sore will be really helpful. You can simply attach/upload it to the reports section of this web page.

Regards
Dr.Lekshmi
