Please tell me, could i use betnovate of gsk pharma to get rid of itching and burning sensation around privy parts?

Get checked out: My recommendation is that you get the problem looked at for a specific CAUSE and treat that instead of just symptoms. For one thing, your private parts may not LIKE the chemicals in that medications and you could make things itchier or worse. For another, without treating the cause such as a fungal infection you're simply inviting the thing to become more widespread and involve other body parts.
