Hi Panda
You're poor DH - it's hard being a DH who hates fussing/getting anything done that might cause other people to get stroppy :-)
I will bullet point because waffle is easier to read bullet-pointed...
1 - Co-amoxiclav and Augmentin are one and the same. Yes, it's a great choice, usually sees off everything that straight amoxicillin won't. (augmentin is amoxycillin + clavucinic acid), but you need to know what you're fighting, and you need a serious course..maybe 7-10 days not 5 for something like this. depending on whether it seemed to help at all to start with.
2 - IF it's still just otitis externa (outer ear infection) then the drops might keep it in check, but not completely heal it, esp. if it's an unusual bug (e.g. DS2 got haemophilus for some reason, and that needed systemic/oral antib's. )
3 - Drops will not work if it's a middle ear infection,and yes that would mean the ear drum has burst. It should heal by itself, but maybe it can't if the infection keeps going.
Qa - did the Augmentin have any effect? did it seem to calm down then fire up again? How many days, what sort of dosage? was his compliance good? Did he take them right way, and finish the course?
Qb - have the drops had any effect - as/above?
Qc - Does he have a family history of difficult ears?
Qd - do you know what prompted it - swimming? flying? general cold?
Possible solutions:
i - He definitely needs a swab doing. I hvae had a life time of ear problems - although mine are as a result of a kind of benign ear tumour, for which persistent ear infections are an indication (I am NOT suggesting he has this!). The swabs can come back with surprising results. IE my latest came back not sensitive to very strong/interesting antibiotics that they sometimes use, but sensitive to amoxycillin. this is just to explain why it might be useful. It may need a different group/type/approach, a 10 day course of augmentin, a short course of a cefelexin, bactrim, which is old-fashioned, but can be taken for a long time. One of my DSs (poor little sods have both inherited my ears) had bactrim for 28 days. None of this should be tried (imvho) without a swab first.
ii - If it makes him feel better, you could just write a note on his before, for him to sign (I know, I know) and hand it in to the surgery saying he didn't want to take up any more valuable appt. spots, but would appreciate a referral to the ENT clinic. Mine used to run an emergency clinic couple of times a week - you sometimes sit for ages, but you get to see people who know their stuff. If he's been suffering this long, it will be worth it.
iii - most useful would be for GP to do the swab, and then give him the referral. That way the results will be back by the time he sees the ENT.
iii - This is for you - tell him that if he can't stand it any longer, then do something about it - ie ask for one of the above - but if he won't, you don't want to hear another word about it!
and (in a shouty voice) stop blowing your nose Panda DH!! If you must, Gently blow one side at a time.
Hope you get some respite soon., Both of you.
