Throat Swelling And Infection

I have some problem with my throat lately. I'm so worried. This is the 3rd time I'm taking antibiotics in October itself. Remember I finished the 1st course early Oct, seemed to recover but after 2 days, it was swollen again! I then went for the 2nd course which was stronger than the 1st course. It was the same. Subsided for 2 days then it came back again. My God! What happened to me?

Whenever the infection is back, I'll feel dizzy and headache. Maybe caused by the connected vein. I visited the doctor just now. Doctor said the infection has not been subsided so far since the first day. She advised me to take one injection on my butt. Phew! Luckily it was not so painful, but this made me recall those days when I was jabbed once a week for 6 weeks during my pregnancy of my little Zhen Nam. That was really painful....shichhhh....

The doctor prescribed some more antibiotics for me, and this time a longer period. I've taken any of it because still doubt whether to take because this will be my 3rd time in this month. I'm worried that I'll lose my body resistance. I'm trying to see whether my condition will be better or not tonight. If not, then I have no choice but to start consuming tomorrow.
