I usually walk 3 miles a day (other than at gym), whereas at the gym I stay on treadmill for 20 minutes juggling between walk, jog and sprint.
When I run quite for some time, I get a shooting pain at the right side of my abdomen! Not just this, at times when I walk quite a lot in any environment I get the same kinda pain. Also, the issue is not steady, it happens only when I breathe IN. And only till I am breathing little heavier than normal.
So, what might be the cause? What precautions should I take to not let this increase? Above all how do I make it right?
P.S - I don't remember this happening even once when I lift weights.
Weight - 95 kg. Height - 185 cm. Been working out irregularly for 4-5 months.
