Life is just not easy anymore. A pedicure once a month is not enough. You need to take care almost on a daily basis. E.g. simply relaxing your feet for ten minutes in a bucket of hot water can do wonders for that aching tired feeling. You may also add a little salt to the bucket for better results.
Epsom salt is a good remedy for a strained ligament or a muscle pull.
A footbath is also an excellent way to restore circulation in case you feel numb or cold. Just in case you do, here is a word of advice. Never, ever handle these problems by yourself. Because seemingly simple problems tend to worsen if handled in the wrong way. Always consult your doctor or a chiropodist and get the right advice.
