I ran a mini marathon 2 weeks ago and now each foot has a calas type sore on it and they are extremely painful when I walk.  What could it be and what do I do to make them go away.  This is my 3rd mini marathon in 3 years and this has never happened before.
Dear friend don't worry. The pain may be musculo-ligamental type, that may occur due to sprain after much walking/running. It will subside in few days by its way. You can take analgesic like ibuprofen or if severe pain combination of diclofenac + paracetamol + chlorzoxazon/serratiopeptidase for temporary relief. For severe symptoms got examined by your family doctor first. Hope this answer will be helpful to you. For more queries please don't hesitate to ask. Get well soon.
