So recently I've felt really really weak. Along with extreme tiredness and achy body! I'm obviously going to get into the doctors next week but I was wondering if anyone has ever had the same and what was the outcome? I have an under active thyroid to (I'm 30) The past 3 nights I've woke a few times to gulp a glass of water! I was in work this week and I had a rush of extreme weakness all over my body to the point I had to sit down! Followed by achy hips and extreme tiredness?!
