I'm 28 years old and otherwise in general good health.
Over the last few weeks I have been experiencing extreme fatigue. It comes over me suddenly, usually in the afternoon. I feel absolutely exhausted, I cannot think straight and all I want to do is lie down. Even simple tasks such as having a shower completely exhaust me to the point of tears. During these times, which last between 30 minutes and a few hours, my heart races and I sometimes get headache.
I'm not sleeping well at night. I'm having vivid dreams and my mind is racing (but nothing of any note just stupid nonsensical stuff).
This weekend I felt like I was getting flu or a virus. Alternating from red hot to shivering, sore throat etc. But nothing really came of it.
Today I ate my tea (appetite is fine if not a little more than usual) and as i finished the fatigue hit me again. I could cry. My lower back is also hurting.
I'm 5 ft 2 and 150kg so not overweight.
Any ideas?
