Note
A cautionary note today... A friend's Mom banged her toe, and it stayed discoloured over a period of months. Her toenail split in two during this time, but neither she nor the docs got too concerned because of her traumatic injury. It took almost a year before someone recognized it as a melanoma. Her big toe has been amputated, and she awaits results from lymph node tests to see if it has spread.
A lot of us bang our fingers and toes on a regular basis, but make a note to keep an eye on any dark marks under your nails. Apparently, subungal melanoma tends to look like a streak, and it is often under a thumb or big toe nail. If you can't remember an injury, or if a dark spot seems to be getting larger, see a doctor.
Orienteering race 58:48 [3] ***
ahr:156 max:220 rhr:53
Peak-2-Peak race on a fantastic autumn day. (Although you gotta wonder, should it really be possible for people to stand around in sleeveless tops in Canada in late October?) I haven't orienteered much this year, so it was great to get out in the Dundas Valley and get some practice before RTH. Unfortunately, I got a heart arrhythmia just after #4, so I walked much of the way to #5 with the usual feeling of doom. It occurred to me that I was wearing my HRM for a change, so I glanced down and noticed that I was up to 220. When walking and deep breathing didn't do the trick after 5 minutes, I finally tried Valsalva, and that stopped it immediately. Interesting to watch the instantaneous drop to 124 on the HRM. After that, I was feeling cautious, so I ran, but didn't push it. (Hard to do in a race where the entire point is to find controls on hilltops!)
This isn't the first time it's happened, and when I had all the cardiac tests a few years ago, they insisted that they found nothing interesting, even though there were hints to the contrary. The cardiologist said she couldn't guarantee that endurance exercise wouldn't kill me, but she figured that giving it up was more likely to be harmful to my health, so she wouldn't advise me to stop. Regardless, I'm doing some googling on arrhythmias and hoping that it's paroxysmal supraventricular tachycardia, which sounds bad but is supposedly "not usually dangerous and tends to occur in young people - can happen during vigorous exercise". Not that I'm terribly young, and not that I was exercising that vigorously, but maybe by medical standards, I'd qualify for both.
I'll be looking back on my log entries if this happens in future, so here are a few possible factors - just getting over being sick, coffee in a.m., poor warm-up.
Other than that annoying, scary incident, it was a fun day out. Great to see good friends and practise navigation in more difficult terrain than I've been in recently. In spite of the heart thing, I wish I'd signed up for the long course, since I could have used more practice.
