Fatigue,sensitivity to cold,heat,searching for words happens with more frequency,sometimes I feel
That I have hit a wall.. And just stop or I will drop
I feel like I walk around with a wet blanket over me.
I first attributed some of these things to my meds for a fib/afl..soltol,pradaxa
Yet I have been on these meds for 4 years. The thyroid test for hypo thy., came back within normal
Limits. Heart Doc says unlikely heart meds.
No amount of sleep,relieves my fatigue. I have an appt with an endocrinologist am I wasting her time?
Thank you so much! Mlv
