As a precaution not to get the covid, I went ahead added 1/4 tsp of sea salt to my 1 liter drinking water once a week and started to gargle salt after meals like 3x a day for 2 days. Also for the first time, I tried the foot painting that evening when all of a sudden I develop a swollen node under my chin and a sore throat that started as mild that got worse. Became paranoid and started to wear face mask right away to protect my child and hubby if in case I caught it. I'm now on my 2nd day of the sore throat and I'm kinda feeling some mucus now forming on my chest, so what I do is I gargle with saltwater and cayenne alternate it with providone iodine mouthwash, which didn't seem to work much, so I made and sipped the "stronger solution" from Ted of Bangkok for tonsilitis: 1 tbsp of baking soda (sodium bicarbonate) plus 20 drop of 3% hydrogen peroxide (mine was the cheap regular drugstore brand) then 4 drops of povidone iodine solution in a half glass of water. I am still sipping 1 tspn every time I'm feeling the pain on the throat when I swallow. It has tremendously helped my throat tho I still feels it's there. Hoping to get better by tomorrow. It's the second time now that this swollen lymph node happened to me this month. First was when I puffed out on seaweed (fresh kind) that night I developed a swollen node right away but without the sore throat. I also had added sea salt to my drinking water that week. I wonder if it's the salt that got me into trouble twice or was it the iodine?
