I took Metronidazole on 4th July, the next morning I felt tiredness, pain in my left shoulder and my tempature is around 37.5. I took 2 on 5th July morning and night. And my flight was on 6th, when I got on the flight I just felt very sick and sleepy and feeling of vomiting, and then I fell into sleep for several hours. The next day I felt more ill, my arms and legs were painful and tingling, I was so dizzy and almost like depressed and headache as well the temperature was still around 37.5 and I don't know if it's because of long time flying or because of this drug my feet were very swelling. I stopped the medication already 1 week but I can still feel dizzy, sleepy, tiredness and sometimes pain in my legs and arms. I don't know what should I do? Thx
