Learn English – Use of needn’t in sentences

british-englishgrammar

Are the sentences below correct?

Which is more commonly used in BrE? Do you use them both?

Need without "to", are they possible?

I need go to the hospital to get the special treatments.

I needn't go to the hospital to get the special treatments.

Need I go to the hospital to get the special treatments?

Needn't I go to the hospital to get the special treatments?

I've ever heard that "need" with "to" can be used in all verbs, and "need" without "to" Only can be used in the present, if you want to put "need" without "to", I must put "have" after the "need" e.g. I needn't/ need have gone.

Are the facts correct, I await for your explanations, thanks!

The question is confusing, here are the sentences:

I need go to the hospital to get the special treatments. [no]

Correction: I need to go to the hospital to get special treatments. [corrected]

I needn't go to the hospital to get the special treatments. [correct]

Need I go to the hospital to get the special treatments? [yes] More common usage is: Do I need to go or Have I got to go.

Needn't I go to the hospital to get the special treatments? [yes].

Needn't I go means: Do I not have to go? Have I not got to go?. What is often actually said also is: Haven't I got to go etc.?
