I'm a newbie so after some advice please. I've suffered with tiredness, muscle aches and lack of libido for a number of years on and off, mainly on. Doctors have been unable to find anything despite numerous blood tests and just said I probably needed rest (despite getting 8-9 hours sleep most nights, although rarely wake up feeling refreshed). 6 months ago I felt really REALLY tired again, unable to move from the sofa for a few days. More blood tests revealed slight vitamin D deficiency. 2 months later I was diagnosed with depression and put on Vensir (venlafaxine). Although Vensir has helped my mood somewhat, my energy levels are still at zero, vitamin D seemingly making no difference. After researching hypothyroidism I do seem to have a number of the symptoms, in particular the above and dry itchy eyes with dry skin on my face which I didn't think twice about. However some of the other symptoms I don't really have, or could be as a result of being on Vensir.
I don't know if the doctor has checked my thyroid with all the blood tests I've had - is it routine to check as well as vitamin levels, iron levels etc?
Does hypothyroidism cause the same symptoms all the time or could they fluctuate slightly over months/years? Are there certain things such as libido which are generally affected first?
I'm 36, don't smoke, drink on occasion and of normal weight. I have a varied healthy diet so shouldn't be deficient in anything. Up until the tiredness really set in I would go to the gym regularly but I've had to stop because of the tiredness.
Many thanks for any advice you can give
