You need to see a physical therapist only if your physician determines that doing so is necessary for management of a problem.
It is always a routine recommendation that a healthy person over 45 years of age should have evaluation by your primary care physician prior to significantly increasing physical activity. See your PCP earlier if there are specific factors that increase risk of heart attack such as smoking, diabetes, high blood pressure, high cholesterol, or family history of heart attack or stroke at age younger than 50.
Otherwise most wrist injuries gradually improve with time and benefit from partial rest. A non-compression wrap or splint is helpful if it enforces partial rest.
In the first 1-3 days, a compression wrap may be helpful to limit swelling. There is no other benefit from compression and after 2-3 days there is absolutely no benefit at all from compression.
Pain that has not been improving and completely resolved by two weeks after injury needs evaluation by your primary care physician.
Muscles exist in pairs with one muscle performing the opposite function as its pair. The strengthening regime needs to restore the proper balance in these muscle pairs.
Doing so will reduce the risk of injury and improve performance.
