No one can cover up the natural truth! Bodily pain, any sort of aching is suffering for sure. No matter who is feeling this, whether Buddha or any lay person always shall feel physical pain. If and only if, any tranquilizer was used, the person may not feel the pain. So Buddha clearly feels the suffering. Because suffering does not have only one origin.
All sufferings do not depend on attachment...For bodily pains no attachment can be shown as an origin.
Lets all be mindful,
