First liver cleanse and day after pain in right side of neck and right trap muscle. Been a week and pain has not gone

I'm really worried I have done more harm than good. My mum done one months ago and didn't do the prep and produced lots of stones

Last Sunday I did my first liver and gall bladder cleanse. Did the prep of 5 days drinking apple juice and tried to cut out processed meats so ate fairly healthy

On the sat did the cleanse. Ate oatmeal breakfast and for lunch rice and veg.

Did everything as normal for sat did 4 tablespoons of Epsom mixed in 24oz water. Wasn't sure if was meant to be teaspoons as some say tablespoons and others teaspoons

sun at 5 am severe diarrhea just yellow water
Did Epsom salt drink at 6 am

Constant yellow bile diarrhea with no stones about 4 times before 8am

Tried to drinks the last glass of Epsom salt at 8am and was sick straight away. Couldn't handle no more Epsom salt, constantly going to toilet and just lots of yellow water

Only about 10am I produced a very few tiny tiny green stones. After that another 6 times till about 2pm just yellow pure water diarrhea with no stones

Completely killed me doing this I could no way do this flush again did not agree with me

Felt ok in eve and next day felt ok

Tues woke up with a really sore neck on right side and right side trap shoulder muscle. Felt like I been in a car accident and got whip lash

Been a week now and the pain has not disappeared. Hurts when picking stuff heavy and hurts to much doing press ups

I can no way do another cleanse it was to much. Kidneys also hurt a little for the whole week still. Have i got something stuck as no big stones came out in flush only a few tiny ones in only one visit to the toilet of about 18 x on the Sunday

I have even booked a appointment tomorrow with a osteopath to see it's a trapped nerve

Please help I'm really worried
