Kali iod tituration 3x. Spondylosis!

I have chronic ear and sinus problems for last several years, including swelling in mastoid and pain. No discharge from ear, but all other symptoms are of mastoiditis and chronic otitis media. I was suggested Kali iod tituration 3x which I read is very useful medicine in sinus disease. But because I have been a hypothyroid patient for many years in the past (now tsh and free t4 is normal, and I am not on thyroid medication) , and this medicine is potassium iodide which was suggested in a scientific website to inhibit thyroid activity, I want to ask if I can take it. And if I can take it safely, what must be the dosage and duration of treatment. I also have vertebral hemangiomas in c4 and d2 with cervical spondylosis
