Welcome to HCM.
The major risk factor for varicocele
is obesity causing abnormality in the drainage
of testicular veins leading to dilation. There is no evidence of smoking
causing this. There are many treatment options available both medical and surgical. I would suggest you get in touch with a surgeon who can examine you in detail and give appropriate therapy.
Over the counter painkillers can be taken if there is discomfort.
Smoking predisposes to many other serious conditions when compared to varicocele. I would suggest to quit smoking as soon as possible.
