I (29 yrs old, female) initially had pain occasionally in my left foot, which followed only after a lot of walking or carrying the kid for long. When I consulted the doctor, he said that I have a kind of flat foot. He adviced me to have tendocare- once daily for 3 weeks. After I had the medicine for 5 days, the pain increased so much so that I am barely being able to walk properly now. Curving my left foot's thumb towards the body, makes me feel a sensation that is close to a pricking nail (at the point the foot has an arch). The pain is continous (even when I am not walking), getting unbearable & disturbing. Please suggest urgently.
