charlajustin hi there wowie what an experience woulda scared the shitters out me that one...... But i had a similar experience yrs ago when i got in some hot tub spa thingo!! Stood up and PLonk..... I rekon or my theory is maybe were so tense all day long 24/7 that when we do relax IE bath hot tubs its like having a hit all at once.... I've never step foot in one again after that either....... with a shower im not sure about you but im in and out quick..... as with baths you relax there etc..... hope ur feeling better anyhow......

Btw im a newbie hello
