Salt question

Hi, would be grateful for any help on this - I was taking a low dose of Iodine following the low protocol and got up to about 3mg over a 3 month period. I had to stop 6 weeks ago due to very bad detox symptoms. These are still quite challenging - tiredness, sweating, tingling, palpitations, flu like symptoms, I have been unable to work. Would salt help with this even though I am not currently taking iodine? I am still taking mag, selenium, vit C, B complex. My doctor has told me I have a virus based on swollen lymph nodes in the neck and raised white blood count. Thanks.
