A new perceived reduction in the size of one testicle, particularly when associated with episodes of pain, should not be ignored. There are several possible causes, including previous inflammation/infection, varicocele, hormonal or vascular problems, and less commonly testicular atrophy. The reduction in morning erections may be related or may be an independent issue; it cannot be used to determine whether the testicle is shrinking. Any new change in testicular size, shape or consistency warrants an examination.
Next Steps
I would recommend an examination, rather than waiting to see whether the size changes further. Depending on the examination, a scrotal ultrasound with Doppler may be useful to objectively compare both testes and assess blood flow, varicocele or other abnormalities. Do not assume that surgery or any particular treatment is required until the actual cause is established.

Health Tips
Avoid repeatedly squeezing or measuring the testicle, as this can increase anxiety and cause local tenderness. Wear comfortable supportive underwear and avoid significant trauma to the area until you have been evaluated. If you develop sudden or severe testicular pain, swelling, nausea/vomiting, redness, or a testicle that suddenly sits higher than usual, seek emergency medical attention immediately, because testicular torsion is a time-sensitive emergency.
