Your story is quite familiar to many on the forum and swelling is one clinical symptom and I'll link below others as your GP may think they are separate from hypothyroidism when maybe you need a rise in hormones:
Pleural effusion and consolidation on the lung (or pulmonary consolidation) are usually caused by infection. Have you recently had a chest or lung infection, pleurisy or pneumonia?
There is wet pleurisy and dry pleurisy, wet pleurisy is where the normal amount of fluid around the lungs increases abnormally and is known as pleurisy with effusion.
I have recently had both pleurisy and pneumonia and they had nothing to do with my hypothyroidism .
Haven't had a cold or cough since Dec 15, that was a bad chest infection. But nothing more since.
Docs are treating me with strong anti biotics so hope that clears this up.
Wasn't sure if it was to do with my heart not working properly due to the thyroid and therefore not pumping the blood round and collecting excess water along the way. My legs and ankles were also full of fluid which I have been given a diuretic for.🙄 (39 yrs old in a 79yr olds body) :))
Hope you are feeling better now and your infection has all gone.
