Hi,I'm 28 yrs old.I have been working out a lot more than usual, lately and after following a fitness routine my foot started to feel sore and I have noticed few knoted spots right under the arch of my left foot.Its slightly pinkish in color and when I touch it I can feel like a lump underneath.Can walk on it okay without limping but its slightly painful. Have also noticed a slight bulge on the left side of my left foot and its slightly hard when compared to my right foot. What does this mean? should I continue with my normal excersice routine? I have started working out after a year since my post delivery. I have been following this excersice routine prior to my delivery and did not face any consequences like this before. Kindly advice me what I should do ? Thanks.
