Rest (from computers, high tech gadgets , phones, in fact anything that involves small clicks – hard these days I know) would be beneficial.
I’d also see your doctor and get advice on taking some anti inflammatories. I’d also see a physio (you may have to hunt around for a good one) get some ultrasound
and massage on the forearm extensor muscles (most likely to be causing your finger pain). You should also try not to panic, stress is a trigger for tension which is a trigger
for RSI pain. You also need to get an ergonomic assessment done. Your employer has a responsibility to provide you with a safe ergonomic setup. It is most likely that
your injury happened because of a combination of bad ergonomics with an extended period of typing in a stressful environment with minimal breaks. From an ergonomic point of view, I expect ‘the claw‘ may have come into play too, so its important when you go back to work not to use any un-ergonomic practices that led you to this injury.
You also need to religiously take breaks when working, introduce stretches and small micro breaks from typing, get up and move around more. There are break reminders available for free download.
If your job involves text input (rather than say programming commands) then consider a voice recognition system. Also consider a physical pastime that gets your arms moving better like swimming , kayaking or yoga.
Also read over my FAQ section and ‘breaking the RSI pain cycle‘ sections here (if you havn’t already).
Keep in mind that you have caught it early, and hence you have the best chance of doing something about it.

Best wishes.

I’m glad to hear this works for you. You are fortunate that you caught it in time and made those adjustments required to your working practice.
RSI need not be a career destroyer if it’s recognised at an early enough stage.
There are many more of us out there that took too long to discover those adjustments, and are now in a more permanent state of RSI pain.
The education of the small adjustments need to take place at an early stage of our lives ie. in schools.

I havn’t tried acupuncture for this condition. I was offered it a few years back, but didn’t like the thought of it more than anything.
Recently I have had some for other ailments, with some success. I may get around to trying it for my RSI at some stage.

there is no universal solution that fits everyone. Everyone is built differently. Advice from a professional ergonomist is required to find out what will suit you. In my case (before I gave up my full time job anyway) I was using a drop down (fully adjustable) keyboard platform by Humanscale, a straight keyboard but with my wrists trained to neutral and a Contour roller mouse. If you check through my other posts on the site you will get more info. Try ergo equipment out before buying and please get some advice from an ergonomist. There are a lot of factors that can cause RSI, and everyone is different, so there will be different answers to your question from everyone who has gone through this. You also need to look at exposure and workload as well as other factors. Remember you can be sat in the most ergonomic chair at the most ergonomic desk with the most ergonomic mouse and keyboard and still be at risk of RSI if you don’t use them properly. Especially if you don’t ensure your posture is good. Sorry for the vague answer, but it happens to be the truth.
