Pain I think its My liver

I’m been in so much pain for 3days today
My pain is on my left side above my waist it feels like soreness on the inside
I did a ten days Master-Cleanse and the moved on juice & cooked veggies and p&b shakes after 2 days of this the pain started I’m drinking lots of water about 90oz a day
Is this my liver it hurt to talked loud it hurts to breath deep and I’m very very sleepy should I go to doctors or is there any thing I can do .
Thanks for your input
