Thanks for posting your query.
White bumps on your right side of the tongue that hurt are most likely caused due to constant irritation of the fungiform papillae.
Allow the soreness to run its course, and wait for natural healing. The only practical solution to quicken healing is avoiding irritation to the affected tongue area, or else pain symptom will worsen. Say no to hot drinks (tea, coffee), acidic food and sweet goodies. All these can aggravate painful tongue sores.
If it persists I suggest you to consult your dentist
for thorough examination.
Hope I have answered your query.
Wishing you good health.
