For the past 8-10 months I have tried running 5-6 times but as soon as I complete 4-5 days of running there is an unbearable pain in my tibia bone. And due to this I have to take a rest for nearly a month . And now I have started to walk for 2kms daily and with a bunch of exercises but again after walking there is a slight pain I can feel in my tibia bone. So, please help me to get rid of this problem. My age is 25, Male and my weight is constant at 75kgs since 3 years.
