For a while now (the past month of two) I've had near constant low level flu like symptoms (aching joints, sore throat, head ache, feeling cold and feeling tired). This coincided with a drop in my performance and, for the past month or so, has meant I've done hardly any training at all (which is starting to get frustrating). I don't think it's an actual infection in part because of how long it has lasted, but also because it comes and goes (it's there more often than not, but occasionally I'll feel okay).
I'm going to go see my doctor, but past experience has taught me not to expect much. So I was wondering if anyone else has experienced something similar and, if so, what it was/what helped?
