Can I get a waiver for Varicocele In right testicle?

What's there to tell? You don't have a medical condition unless it was diagnosed by a healthcare provider. You should never lie at MEPS, but you should also never volunteer any information they didn't specifically ask for.

I don't know if anyone here can answer that. My own ignorance makes me wonder if your condition even requires a waiver.

Here's what could happen. During the physical, the practicioner will halt your progress and flag you if there are any medical concerns that are part of some pre-determined list. At that point, the recruiter will let you know if it's something that is waiverable.

If you haven't already done so, gather all the documentation you can get from your doctors regarding your condition and treatments. If you do end up needing a waiver, you will need to produce those; night as well be ahead of the possibility

Yes. That won’t be a problem. You shouldn’t even need a waiver. A varicocele is not a disqualifying condition.
