If you have done any internet searches on back problems/pain you are getting adds for all sorts of crap.

Clear your search history and see if it stops. HIPPA violations are costly so I doubt that is the problem.

My area of knowledge is not backs but, I do work in surgery.

HIPPA only applies to certain parts of your record. Those parts are stripped out and the rest is sold.

I would agree that a web site visited, led to being targeted for the advertisement.

That is exactly what I was thinking. I can even look something up on my phone and I will see ads on my laptop.
Not to mention, in some of the data breaches, you may have had a record of who you paid for what.
