I was suffering from cml from last many tears My bcr abl came to 0 after couple of months of treatment . Since then it's always below zero. From last two week I am suffering from weakness and headache and swalling below eyes. I go through all the test and all are normal I also took vitamin d supplement but no improvement in weakness. I am taking veenat 400 once in a day. Just to know its side effect of imatinib or something else? Also if it's side effect then what will be the next step Either it's negative sign to me or positive? Please help me
