Hi I m a 50 year old male,a truck mechanic and off road motorcyclist and have had 12 hard days of working. Now I have been to the doctor 3 times complaining of fatigue, Swollen glands under my jaw,a massive appetite, some weight loss, tingling in my hands whilst lying down using my phone,sleeping 12 hours and still no energy,sometimes I sneeze,my knee joints a sore and it hurts to walk and then my chest seems to tighten up. Doctor put me on Calvepen 666 as he thought I may have upper chest infection. Any ideas?
