that's insane there are no particular signs in you of strong bacterial infection he's given you a antibiotic-nuke with possible side effects. the least it can do is to worsen your diarrhea and wipe out all the good bacteria.
Find a different Doctor..
The doctor has given me teva-levofloxacin
if by medication you mean Ibuprofen and Tylenol (Paracetamol) that's not really a therapy, only a palliative to reduce the symptoms. anti-inflammatory. Paracetamol in particular is used to reduce fever, it's not necessary if the fever isn't sky high but maybe it can help you to sleep.
well if you've been in a crowded place at the Regatta you could have caught a flu there. other sources of infection are from raw food, bugs, cuts etc.
if you keep having diarrhea you should integrate with a lot of water and enough salt. without salt the body can't hold the water. also yogurt with probiotics. and if you're brave enough try the garlic thing for the cough!
I did go to the walk in clinic today and the doctor did say he believes it might be a viral infection and I got a prescription for a pharmacist. So like Gio77 said that explains why medication isn't really working. Uhm the only place I've gone recently in the past month was the day before I began to get sick, I was at a rowing regatta in Toronto all day. No where unusual though.
sounds like you caught an infection, maybe viral. it is disturbing your nervous system too.
check your heart beat rate, your blood pressure, temperature, if values aren't crazy out of range you shouldn't worry.
you could see a Doctor show him that rash and do Complete Blood Count + ESR.
do you remember doing or going anywhere unusual in the past month?
if it was a "flu" you can't do much but wait it out, antibiotics are useless if not counterproductive. try chewing sliced garlic for the cough it can help.
rule out type of infection may be dengue fever as there is rashes seen on the body...
