Shoulder Sprain... should i be icing or heating it after a week?

Hello,

According to the urgent care, I have a shoulder sprain. The x-ray they did showed no soft tissue abnormality and no fracture/ joint issues.

I understand that for the first couple of days I should ice it to decrease inflammation and such. However, what about after a week? should i still be icing it? or should I use heat pad? or alternate?

The sprain isn't too severe i think because I can still have my full range of motion... just at certain movements, my shoulder feels "off" and pain (but bearable). For example, i do have discomfort when i move from typing on a keyboard to moving my hand to use a mouse.

It should recover in another week or so?
