Transverse position

My gyn wants to change the transverse position of my baby. Who went through this? Is it painful? And does the baby stays in his changed position till the end? My gyn and some other ladydoctors are so positive about this… However they said to me that they were are also doing an experiment with transverse positions of babies… Soo confused… My brother has worked at this department for some weeks… He said that he saw it once and it was really painful for that lady…I don’t know what to do…
