I am a 45 years old working female, since last 15 days I am experiencing pain in my left back and left stomach region. I tried constipation medicine, but its not working. I have earlier taken a sonography to check for stone which was found to be normal. Is this the cause of blockage in intestine, because I am in a habit of eating chalk, (suffering from pica) when I get tensed. I am also neglecting my food since now I am staying alone and finds difficult to cook proper food. Please advise home remedy which may ease my pain.
