Hello, I need to know from where can i get the black fungus testing done for my MIL. She had her cataract+retina detachment surgery last year in November and since then she is feeling little pain in her eyes and cheeks. Her eyesight is better but still has haedache and cheeckache. She has few symptoms of black fungus like headache, cheek swelling , toothache but no fever, bleeding or any blackened on nose.
