I am 63 and have been taking levoxyl for 36 years. Started out way back on 1.25 and through the years have gradually had dose reduced due to age, menopause, etc. About 4 months ago, TSH was around .25 so I was changed from 88mcg to 75mcg. I rarely notice a change when thyroid meds are changed. This time, I'm noticing what I think is fluid retention, sore breasts, bloating, bowels not quite right. I've gained a few pounds which isn't that big of a deal since I've been underweight for many years. Sodium has been slightly lower than normal. Do you think the change in the levoxyl dose could be causing these changes? Thank you!
