I've been practicing guitar casually for a few months, without a tutor or teacher. I'm starting to be able to play chord progressions slowly, but after ten or fifteen minutes, I feel pain in my fingering hand, especially the forefinger and knuckles.
Edit for clarification: The flesh of my fingertips is rarely sore; it's more like joint pain, for instance in the hand near the bases of the fingers. My guitar is an approx. 35-year-old Ovation Legend; when I had it serviced & restringed they knew a beginner would be playing it. I don't think any parts have been replaced. It looks exactly like this one:
I'm interested in bottleneck slide, so I'm going to try that and see if it's less painful.
But what are my other choices? I've heard an acoustic with nylon strings, and electric guitars, are easier. I'm also interested in pretty much any stringed instrument you can imagine. Before I start renting & buying things, though, are any of these likely to be easier on the fingering hand?
Another data point is that I'm in my late 30s and work with computers for a living, so I type a lot and probably my hands are wearing out faster than normal.
