Welcome to HCM.
You seem right.
There is possibility of pseudomonas nail infection
Pseudomonas bacteria usually attack the injured nails.
The affected nail becomes greenish.
That is why it is called green nail syndrome
Green nail syndrome is caused by an infection with Pseudomonas , species.
It usually develops in people who have onycholysis
and whose hands are often in water.
The nail in the area of onycholysis becomes greenish in color.
The affected nails can be treated by soaking in a 1% acetic acid
solution twice a day or by trimming back the nail and treating the area with an antibiotic solution.
Broad spectrum antibiotics may be taken for long time.
I hope you got my answer.
