In 35 years of walking I've had three mountain incidents. Two bites have resulted in me spending several weeks in hospital. Only one incident per decade, doesn't seem too bad to me.
One injury which shouldn't have happened was tick toxemia. In Nadgee on a dawdle from the Ranger's Station at Merrica River to the summit of Tumbledown Mountain (325m) I was bitten by a tick. One of the simplest walks up a hill that I've ever done, 6 kilometres each way to the summit and back. Just a dawdle.
I went to the local health clinic several times after returning from Nadgee and couldn't convince several foreign trained doctors that I had removed the body of a paralysis tick from the back of my leg, but I couldn't get the head out because it was now too deep. Several times I was told, "Ticks don't burrow", even asked by one doctor, "What is a tick?", "It is an infected hair follicle" one doctor said, "If you think there is a tick in there it will eject itself eventually," said another doctor. I kept telling the doctors otherwise. On the fifth day after being bitten, I collapsed on the lounge room floor, and was leaving this planet. My wife returned home from her work during her lunch break to check on me because she was concerned that I was not well, more ill that morning than any of the other days. She got me into the car and drove to the medical centre and a doctor with experience of venomous local wildlife said, "He looks like he has Tick toxemia, have you been to the coast recently?" I can remember my wife saying, "He has been telling the doctors here, that its a Tick all week." In hospital, a couple of days later, one of the doctors told me, that I was so toxic when I was admitted that the medical staff thought that they had lost me. I'm lucky that I slept through the whole drama ... and I'm too evil to die.
The next bite was back in March last year, I brushed a log on the Boyd Plateau and was bitten by a Redback. Four days after being bitten I had an extreme reaction to the bite when the venom finally reached the lymph nodes in my groin. I ended up in Calvary Hospital for 11 days. Now 10 months later, I'm still on medication. Last visit to the hospital, just a few weeks ago, a doctor said, "There appears to be residual venom in your body." The doctor was thinking about giving me some sort of antivenin. Thankfully that didn't happen. I've had enough of being poked and jabbed thanks to a little Redback.
Two decades ago I slipped in the rain on that thin side sloping conglomerate ledge below the wall of the Castle in the Budawangs. That last narrow ledge before walkers start the climb up to the saddle. There will be several here who know how slippery that ledge gets when wet. I was going down until my forehead struck a sturdy horizontal branch of a snow gum several metres below. Hitting the branch stopped me dead. I almost always walk alone, but was with my wife that day. Helen kept saying to me, "Are you alright, are you alright?" I kept replying, "Don't ask me, don't ask me if I'm alright, stop asking me or I will be hurt!" I photographed a rodeo clown at Bungendore once, and I asked him, how often did he get hurt, and did he get seriously hurt when hit by bulls. He said to me, "I'm always getting badly hurt, but I say to myself, I'm not hurt, then I get up and run. The moment I stop to think if I'm hurt, I will be hurt and feel the pain and then be hit again".
When I'm hurt walking, I'm not ever hurt no matter how much it hurts. The last thing I needed the day, when I slipped below the Castle, was my dear wife convincing me that I was hurt.
The photo was taken near where I fell, near the start of the climb to the saddle. Looking across Oakey Creek to the walls of Mount Nibelung. I've climbed the Castle several times since then.
