I'd been advised to seek out medical assistance this week. Done that and so far I'm no further forward. Currently ticking off every possibility with my next appointment on Monday morning in London. Fingers crossed everything settles down on its own and I can continue with the filming I've got planned on Monday afternoon. Struggling mentally as it's now been three weeks off work, and to add to this I'm missing payments from another site for what is a touch over $1300.
