Hi, thanks for posting your query.
These red spots seem to be a result of pedicure. You have mentioned that while brushing the skin during pedicure it hurt a bit which means that the pressure applied was more than what skin could tolerate.
This caused an insult to the underlying skin tissues or probably the superficial blood vessels leading to inflammatory changes or bruising.
Secondly at age of 70 skin becomes lax, thinner, blood vessels become fragile and the ability to sense touch, pressure,
vibration, heat and
cold may be reduced. Thus, skin is at higher risk for
injury. Rubbing or pulling on the skin can cause skin tears. Fragile blood vessels are easily broken. Bruises, may form after even a minor injury.
To treat the same, she may apply a mild
steroid cream twice a day for a week or so.
Avoid rubbing the area.
If this does not settle or worsens you may contact a
dermatologist for examination and treatment.
Hope this helps.
