I had done root canal a week back and after 2 days I had grape juice and sore throat pain started immediate after that, I am feeling very chronic fatigue from 2 days also, same had happened 2 months ago and had taken glucose, geriforte syrup, some antibiotic. What should be done for this fatigue with legs very weak and trembling, loss of appetite .should I go for cbc, ultrasound normal and endoscopy showed mild antral gastritis with gerd. Any homeopathy cure for CFS or ayurveda. Any test to detect CFS.
