I am a patient of nephrotic syndrome biopsy proven minimal change disease from past 10 months. From the last 3 days I am experiencing sudden severe headache at the back of my scalp. I experienced the same problem when I was taking infograph ( tacrolimus) but when my doctor stopped it the headache was gone. Now I'm taking cyclosporine ( neoral) delta cortril and anti hypertension tablets. I'm also experiencing a relapse for the third time during this disease. What should I do to reduce headache.
