One of the things I do everyday, many times a day, in my profession is designed to prevent this:
That activity is this:
And, unfortunately, that leads to this:
...which bloody well hurts like a bloody bugger!
I get these skin cracks in my thumbs (only my thumbs) as a result of clamping and unclamping the pinch valve clamp on the blood lines that are used in dialysis.
Each set of tubing has 12 of these clamps in various sizes. Most of the clamps will be opened and closed multiple times during a dialysis treatment, from setting up the machines, running the patient for 3 - 5 hours (yeah, it varies that much) and stripping the used tubing off the machine at the end of the treatment.
The only product that I have found that works in treating these skin cracks is this:
I have tried every kind of liquid bandage and skin glue on the market. This stuff works. It is the only stuff that works.
And Johnson & Johnson, in their infinite wisdom, has elected to discontinue it. I went to buy some a couple of weeks ago and couldn't find it anywhere. There wasn't even a spot on the shelf for it anymore. No one, at any of the stores I asked at, could tell me if it was still available.
So I went online, found J&J's website contact info, and emailed them about it. They tell me it was discontinued. I told them they just made many nurses in many hospitals extremely unhappy, as this product of theirs was the only stuff that actually sealed the cracks, stopped the pain instantly, and stayed on long enough (a couple of days minimum) to allow the cracks to heal.
Granted, it is light purple in colour (WTF?) so you look like you have perpetually filthy digits when using it, but who cares! It works! Your thumbs and/or fingers don't hurt on contact with anything any more!
I used to use krazy glue for this purpose. The Liquid Bandaid is actually cousins to krazy glue, except that it dries flexible, whereas the krazy glue dries hard and tends to catch on everything.
I guess I will have to resort back to the krazy glue when this bottle of Liquid Bandaid runs out. Unless miracles happen and J&J changes their mind and brings it back.
