My shower hose is stuck...not so simple

[SomeDayCame]

2002 570 Voyager. Master head shower is a one piece unit. The shower hose coming out of the shower seat worked just fine until a few weeks ago. Now it seems somthing has fallen or wrapped around the hose. I cannot fully extend the hose. I cannot find a place to access underneath to check what is catching on it. Any clever thoughts on how I can fix it without completing taking out the head?

Can you get at that area through the cabinet under the master stateroom sink? If there is not a removable panel on the forward side of that cabinet, maybe you can cut one out to gain access.
