Is all pain the same?  Pain is personal.  No one can feel your pain.  Whether it is internal or external pain.  People can emphasize based on what they have experienced.  But only Jesus can truly understand.  He bore all of our pain on the cross.   
“Surely he took up our pain (griefs) and bore our suffering (carried our sorrows), yet we considered him punished by God, stricken by him, and afflicted.  But he was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was on him, and by his wounds we are healed.”  Isaiah 53:4-5
You can take all your pain and suffering to the one who understands and who has healed you. If you want healing to manifest in the physical, you need to not doubt the work Jesus has done for you on the cross.  Receive it today.
“And whatever things you ask in prayer, believing, you will receive.”  Mathew 21:22
