I'm 45 day clean from Meth abuse and have untreated Hep BorC, recently got over the flu, and now have swollen glands near my mouth or throat and suffer from fatigue amd muscle soreness. I know some a detox related but is there a larger emergency?

Seek care. Your current symptoms are compatible with flu. Please note that both Hep B and Hep C are curable and you should seek care for your long term health. I applaud you for kicking meth!
If the glands more than double in size, ulcerate, bleed, you get fever, or lose weight, see a doctor at the earliest.
Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex.
