A. whenever you are taking any medicine which has been given by your doctor you have to wait and watch for three days and follow the instructions given by the doctor and if there is no improvement after three days then take a follow up. so kindly take a follow up with your doctor who will tell you whether any change in medicine or any other investigation is needed or not . in your case a medical examination is required for proper diagnosis and treatment.d difficult to tell without examination whether it is normal or not.d advisable to remain in contact with your doctor for proper guidance and treatment
