We’ve had this a couple of times (until I told him: stuff your privacy, I’m supervising the willy wash until you’ve learned to do it properly - and after a few weeks of that I literally still ask every day did you remember to wash it (half the time he says he forgot, the other times he rolls his eyes and says of course I did it).
Firstly: you may still be in time for an online GP private appointment. MedicSpot do until 9pm and email the prescription. Think it cost £50 when we did it. Then an overnight pharmacy can dispense the antibiotics.
So here is what the GP told us. It is either bacterial or fungal. In case its fungal, put anti-thrush cream (like canestan) on the end twice a day). You can buy that from any pharmacy or most supermarkets.
If its bacterial then it is either just the tip (in which case regular rinses with salty boiled water, cooled, may clear it) or it may have progressed up the opening, in which case it will become more and more swollen and painful until you do antibiotics. Don’t be too fobbed off by the nurse, the NHS is completely broken and basically we now either pay for private care, or get inadequate care, is the current situation.
If you’re on holiday anywhere in Europe / Asia / America / Australia you’ll probably be able to access superior medical care overseas.
