I used to regularly go to gym and have a great work out and would be perfectly fine. But for the past 2/3 months I have been going to the gym. But the next morning I'd be feeling really rough, I'd have a sore throat, fever and this would persist for 2 days and then after around 3/4 days id be fine again. And I thought this maybe because of winter flu in january, so i just took some time out to recover and started gym end of jan again after 2 weeks of complete recovery. But then same thing again the next morning, sore throat, fever, general rough feeling. And so i thought it was just coincidence so rested for 10 days, gym again and same problem! I'm not sure what the problem is, I doubt the doctor will be able to help me with this so hoping someone might be able to point me in the right direction. I dont fall ill if i dont go gym, and i think i have a good diet, and i do eat some carbs before going gym so dont go there energyless! Any comments and thoughts would be really appreciated.
