how can a new infection occur if already on antibiotics?

[olivo]

I am on antibiotics following a heavy cold which left me with laryngitis and a chest infection. It is day 4 of my 7 day course and I have suddenyl got very painful sinusitis. i thought that the antibiotics (amoxycilin) would have prevented new infection? does that mean they are not working?
and while i'm here, what is the best painkiller to take for sinusitis; i fell like my head is going to fall off!

well not all bacteria are affected by all abs

and also abs can kill good bacteria and lower immunity so a different infection can develop

and some illnesses are viruses which are not affected by abs

ah,ok. maybe i should take some acidophillus to counter act then, or would this mess up the ABs? I'd hoped i was on the mend!
thanks zippi!

i have taken sinutab before now and it has worked

i swear by mega doses of vit c 1000mg

and drink lots of water

steamy shower and blow your nose in the shower

thanks. have just had a shower and it was revolting when i blew my nose!
off to riffle through my medicine box......

hope you feel better

did you have a good day?

salt water up yer nose.

no! still think my head is going to explode, have taken everything i can find in the medicine box. would do some inhaling but my asthma is really bad at the moment and it always makes me wheezy.will keep up the vit c though, i love those fizzy tablets !
. will try and get some saline drops tomorrow.

thanks for checking up on me!

oooh pooor you. the sinusitus may be a result of the original infection anyway, or a secondary.

Try the head over a bowl of steaming water with a couple or six drops of karvol or olbas oil, towel over head. Then blow your nose like this: Block one nostril and blow the other one, just hold the tissue under the nose and dont obstruct the free nostril, I garuntee you will have all manner of snot fall into the tissue, its proper gross - but your head will feel better for it.

Sudofed is best, i think for sinisitus, you can get sudofed + with paracetemol in it too. Dont take with lemsip though as it is the same active ingredient.

Um, can you tell ive just got over sinusitis??

Thanks LEM. have just tried your nose blowing technique - gross!
can only do the plain steaming cos of my asthma at the moment, but will try it later.
i'm off the the pharmacy later to see what i can get.
hope you're feeling better now.

hope you start feeling better

i used to do a lot of head boiling
