Low grade fever and shinning eyes.

I just completed my treatment of tuberculosis on 17 march and from hospital i went to bazaar and drank a glass of orange juice. After  an hour i felt like if i had a fever,then it goes away after taking some rest. Next day,i had a cold like symptoms,like watery eyes,low grade fever. Same situation goes up to 4-5 days.But at night i feel fresh,and in morning when i wake up, temperature rises and it goes up and down all the time.But feel fresh at night. Now it has been 20 days,low grade fever when i wake up and shinning eyes,and sometimes i feel like a pressure on my head. Also I went to hospital, doctor gave me- STAREST PLUS,AZITHROMYCIN,LEVOCETIRIZINE HCl tablet. But it didn't help me. I have no cough,no breathing problems ,no high grade fever. I am feeling depressed now,due to health related problems.
