The vomitting could be due to hot weather or indigestion also.
The back pain would need healing to be continued.
I guess you are charging his water purifier.
Just a thought….whatever healing you are doing dont inform the person about the medium everytime. I dont know if you told them about water.
This is based on my personal experience if you tell people about all the healings….sometimes due to their past they feel more resistance towards any healing
You cn charge oil ghee with Pain Care serum and Balance Serum.
Soaps and shampoos can be charged with ALL CLEAR SERUM and BALANCE SERUM
Regarding clothes…..you can charge with ALPHA MALE SERUM and MOOD UP SERUM one day
Next day charge with PAIN CARE SERUM…
On paper write
Clothes worn by XYZ today….
Energise this paper with each energy for few min.
You can take a normal cream or Pain balm and charge it with PAIN CARE SERUM EFT to affected area and ALL CLEAR SERUM and ask someone to apply on his back twice.
Water charging also you can do one day with PERFECT HEALTH SERUM PAIN CARE SERUM EFT TO FULL BACK BALANCE SERUM
Next day do with TOTAL WEALTH SERUM MOOD UP SERUM ALPHA MALE SERUM BALANCE SERUM And EFT
Please continue healing with patience.
