Need personal consultation for better examination and treatment
Sorry to hear about your husbands conditiion but nly emergency care is the thing that can be done right now. What you can do now: Give him soft and simple palm, feet massage with sesame seed oil massage if the hospital allows. If he is on food give him light dal rice meals mixed with cow ghee. Put some drops of lavender or rose or sandalwod oil on his pillow for helping him calm and heal. Mantras and flute music helps in recovery at very soft volume. If not that you can find music of 432Hz and 528 Hz that will help him calm his mind. Praying that these tips give you and your husband a bit of healing.
