In reply to Simon:
Hello there - mention ticks and up I pop like a bad penny.
Although I'm no medical expert, not that many GPs are when it comes to Lyme, either. So I'll merrily pontificate on what it sounds like to me.
If you have a round red rash around a tick bite, esp. if the centre is clearing, then you have the one and only sure-fire symptom of Lyme disease. Sorry to be the bearer of bad news. Mine came up 2 weeks after I got bitten, so any advice about it only showing up within 48 hrs is Horlicks, I'm afraid.
if you ignore all other advice, do ...
- take a photo of the rash. It might disappear v v quickly. And some GPs reckon that when the rash goes, the Lyme goes. Not always the case... and the photo may be the only proof or evidence that you are/were ill, as the blood tests are very, very unreliable.
- also, keep a symptom diary. Don't feel like a hypochondriac! It's important, esp. if you start getting loads of different symptoms. It's also the best way of keeping track of dates and symptoms, helps you spot cyclical symptoms, and is invaluable in spotting when you're getting well.
Other Advice
DO ask for a blood test anyway. Ticks transmit many other horrible diseases in addition to Lyme. It's wise to check you don't have them too (ehrlichia, babesiosis, tick-borne encephalitis, etc.)
DO do some research and work with your GP. I can help you find some reasonably credible peer-referenced medical journal articles if you like.
DO be aware that GPs' medical textbooks are woefully out of date as regards treatment. If you don't feel better with treatment, keep going back (and let me know, so I can forward you the info I used persuasively to get the proper treatment for myself).
If you feel you can request specific medication, ask for doxycycline, at least 300mg per day, for 28 days longer than your symptoms last (the spirochaetes that cause Lyme are good at hiding and lying dormant). But be aware that although this will kill the spirochaetes, it'll also make you feel crap, might make you sun-sensitive, get thrush, etc.). Sorry.
DO give me a shout. Drop me your phone number in an email and I'll call you in between Poppy's feeds, if you like.
Finally, DON'T be scared. Some folk only get Lyme mildly and get cured very, very quickly. Fingers crossed and get well soon, Simon.
