Must be something about whitlows, Maisie.... I used to have them as a child - 3 or 4 times, always on the same finger and they hurt like
*&?$. At least, I think I had whitlows! I saw three different doctors who all studied my poor, sore finger under a magnifying glass and a good light and announced that they couldn't be sure but it was probably a whitlow ..... Two of them then dosed me with antibiotics and the ?whitlows went away for a while. The third lanced the side of my finger and , having drained some nasty gunk out of it, painted the wound with something that looked and smelled like bitumen, told me to keep it bandaged for 10 days and, if it was a whitlow, that would probably cure it!
It worked. The condition never returned but, if you were to study my medical notes for around 1959/60, I'll bet they still say something like "patient presented with a query whitlow"!
I hope they resolve your whitlow soon; with all your other tribulations it must feel as if someone up there hates you. At the GP practice I used to go to, they had notices in Reception telling you that, if you want to discuss more than one ailment, you must make an appointment for each item on your agenda! One of the docs told me this was because an amazing number of people came in and spent the whole 10 minutes fussing about something really trivial then, just as they were about to leave, would ask about something much more complex that required examinations and tests, etc so a 10 minute appointment would morph into 20 or 30 mins and they whole day ended up running late.
