In april month, a sudden pain started occurring in lower left rib, When i went to the doctor,he does my ultrasound and xray, he told me that their is no problem in Ur internal organs. It feels like my left rib is bigger than my right rib.now the pain has became mild and occurs after every 2-3 days.also excessive gas passing occurs.I am in anxiety that my doctor hasnot checked me correctly and i am still having some problem??? The pain is now less but I am too scared about this pain, please help? Should i visit another doctor?
