I am diagnosed with hypothyroidism and I am taking thyrox 25mg medicine for last 6,7 months. My recent report shows TSH value is 3.6. My vitamin D level was also low , then I was given vitamin D supplement,now it is 57 nmol/ L. But I still have slight swelling just around ankle and it vary time to time. I went to physician but he doesn't give much attention to it. I want to know what can be the reason. It's been 2 month I notice it. My all other blood test parameters are in range.
