The doctor rang me about an hour later and asked about my problem. After I told her about it, she told me to go staright to see her.
At the surgery, she said it was gout until I showed her the bite mark. She then decided it was infected, which explained why it was running up my leg, so now I have penicillin. Hopefully, I'll be back on my nike again soon.
Actually, I used my bike today without pedalling. I couldn't use the car because I can't press the clutch. It's about half a mile down a hill to the surgery and then a fair climb back up. Thank Christ for throttles. I had no chance of pedalling, so we'll have to add that to the list of what throttles are good for. If it weren't for my electric bike, my only other option would be a taxi.
