Riding on trainer with injured finger
3 weeks ago I had surgery to remove a lump from the ring finger on my left hand. It's still sore (though better than a week ago) and swollen. I've had the arm/hand in a sling or at least raised against my chest for 3 weeks & haven't used it for much of anything. Have to wait another week to find out if it's something I should be worrying about, but decided today that I've had enough inactivity and as it's really cold here I'd rather ride my bike (road bike with drop handlebars) on my trainer in the basement than go for a walk.
I managed to get the trainer & bike set up with only minor difficulty. Riding wasn't too terrible, but I had increased pain in the finger & just couldn't find a comfortable position on the bars. My left wrist also got tired/sore, probably as a result of doing nothing for 3 weeks. I also can't get a glove on my left hand but I think before I try again on the weekend I'll find an old pair of gloves and cut open the one finger opening to allow the damaged finger in. The finger is more sore now (1.5 hours after) than it was earlier today.
Any suggestions? Just take more Advil before starting off?
Ride with just my right hand on the bars? I tried it for a while but it was uncomfortable for more than a minute or so. Would raising/lowering the bars help?
Ride sitting upright? That's possible but it doesn't feel like as much of a workout. If I do this should I leave my saddle where it is or raise/lower it?
Other ideas welcome.
