Hi,
I thought I'd comment on my experiences with Carpal Tunnel Surgery. I had both hands done privately about 7 years ago at the age of 37.
It's apparently unusual for both hands to be done together but, it minimised my downtime, and got me back to work much quicker. The initial recovery was relatively quick and the 6-8 weeks time guide is about right. You have to realise that just because the hand appears healed it doesn't mean you can carry on as normal though. 3-4 months later I still struggled to hold a garden spade and drive it into the ground or to lift something heavy as it would send an excruciating pain through my hand, it took about 12 months for this pain to have completely passed.
Living with the after effects though, I sometimes wonder whether it was the right thing to do. My hands disturbed my sleep and the systems would have eventually withered away my thumb muscle but, at the time I had strong hands. Now I can easily open a narrow bottle like lemonade but, a wide rimmed jam jar is a lot harder to get a good grip of, and occasionally this is beyond me. It doesn't continue to affect me lifting anything but my hands do tire quickly. I get muscle fatigue very quickly in hands and wrists now even if I'm doing a simple activity like rubbing butter and flour together for a cake, I couldn't do an 8oz mix without a lot of pain in my thumb pad for instance.
My hands now ache in places they never did before, the thumb pad is a given this muscle is worked really hard but, I also have ache's in the tendons across the back of my hands between my fingers, and the bones between the joints in my fingers often ache. It isn't constant and I have to be conscious of my objectives and my time limits when carrying out tasks. If they are too grip heavy I will really pay for it later in the day.
Carpal tunnel surgery releases a very specific pressure but, the hand is a very complex machine and with each action, there is a counteraction, when you cut the tendon strength that joins the two muscle pads of the hand you remove the shared load, each has to now work in a different way to achieve the same result and it creates other issues and pressures. I would love to see the muscles of my hands now compared with someone that has not had surgery as I'm sure they would differ in their make up.
My advice would be to do some additional research prior to having surgery and only use surgery as a last resort. It's a simple surgeons procedure done under local anaesthetic with minimal surgery complications but, for you, it's a different story.
You have to live with the ongoing niggles created by the release, and accept that it's a trade off between the loss of sensation, numbness and muscle wastage against the aches and pains of the lack of hand strength created by the loss of the ligament support.
There are days when I think I made the wrong decision and others when I'm not even conscious of hand problems. You'll often find me massaging my thumb pads in turn with the other thumb to relieve the ache and tightness of everyday simple activities.
I hope this helps others.
