Suggest Treatment For Influenza , Dehydration And Sore Throat

I ve been suffering from flu for the last few days. Pretty common issues such as sore throat, blocked nose, dehydration (despite drinking fluids constantly). Headaches, sore joints. sleeping a lot. Lack of appetite( all I want to do is drink more). Had diarrhea and sickness for a bit but it s stopped now. On top of this am having allergic reactions, which has happened before. I once thought I had meningitis( had a rash, sore joints, light hurt my eyes and more), went to the hospital and was told I was having a bad allergic reaction to the flu virus. Right now however I m having high temperatures. Night sweats, my mouth and lips are swollen, lips are raw and bleeding, my eyes are red and weepy and My skin is really sensitive. I can hardly smell but my pee is giving off a strong scent too but the colour is pretty normal for me. I ve been trying everything I can think of to get better but am feeling more run down now .Iv been taking lemsip max, antihistamines, throat sprays and yet it hasn t been helping. I m not sure what to do. Please, any advice would be appreciated at this point.
