Hi there. I was feeling really run down for a few weeks and then I had a flu (proper flu). Was hoping that would be the end of it, but two weeks after the bout of flu I still feel really exhausted - so haven t been back to the gym. I kinda feel like only half my heart and lungs are working - ie quite weak. My voice also sounds tired. Feel worn out and depressed and head feels like it could explode (although don t have headache as such). Have had a runny nose the past couple of days and noticed blood in my mucus - and have just had a nose bleed. Any advice?
