Terrible Headache

Two days ago, I had a terrible headache. It started off as a mild discomfort earlier in the day. I should have taken a panadol when I felt a little headache. But I didn't. Reason being, I do not want to be immune towards it. I thought that it would pass with time. Boy was I wrong. It got from bad to worse as time progressed. I bear with the headache although it was getting worse. Dinner for the night was steamed chicken with black fungus. There's ginger and Chinese wine in it. I had my normal portion for dinner. It wasn't much compared to others. After dinner my headache got worse. It got painful to the extent that my nose and eye socket start to hurt. It has been a while since I have such bad headaches. I know this feeling. It's migraine. It was so painful that I took an iron tablet. As I was menstruating, these kind of headaches is often due to lack of blood. After taking the iron tablet, it didn't get any better. I started getting chills. So I had a cup of Nescafé. I start feeling unwell after having about half the cup of Nescafé. So I stopped and went upstairs. The headache was terrible. I couldn't even lie down. So I sat upright. I got really nauseous so I walk towards the toilet. Stood in front of the toilet bowl, but nothing came out. After a while, I walked back into my room. Sat down for a while. I started having goosebumps. Then the nausea came back. I walked towards the sink. Out came my vomit. It was clearly identifiable from the vomit what I had for dinner. The chicken and the black fungus bit could clearly be seen. I could still taste the Chinese wine too. I vomited quite a bit that it filled almost half the sink. I washed it down with running tap. But the drain hole decided to act up and it wouldn't go down. It was turning into a pool of vomit. I turned off the tap, reached my bare hands into the pool of vomit and tried to unclog the sink. Thinking of it while typing this still gross me out. I know it's my own vomit but I still feel gross. It took forever for it to go down. Then a big bucket of water was used to wash it down. After that I walked back into my room. I didn't feel any better. After sitting for a while, like 15-30 minutes, I felt nauseous again. My goosebumps appeared again. I walked towards the toilet. Stood in front of the toilet bowl. My stomach muscles start contracting. First round, nothing. Okay. Second round, nothing. Stomach keep contracting. Third time, out came the vomit. It was still the chicken and black fungus. I vomited quite a bit. I still didn't feel well. I walked back into my room and sat on my bed. My stomach began to act up. This time it was the back exit. I walked back into the toilet and did a big. While pooping, I felt like vomiting. Luckily I managed to hold it in and not vomit all over myself. After that I went back into my room. I took a packet of Chinese medicine ( fong sar yuen). About 10 minutes after taking the Chinese medicine, I felt like vomiting again. I went into the toilet and vomited again. It is still the chicken and black fungus. This time coupled with yellowish greenish stuff, presumably gut juice. All in all, in about an hour and a half or so, from midnight, I have vomited thrice and almost crapped myself during one of the vomit session. I didn't dare take panadol for fear of the effect of mixing medicine. So I tried to sleep the headache away.
