I need to know if my diagnoses of the following symptoms are correct for the I start my research:

Past several weeks that he is having more bruises, or ecchymosis, all over his body. After coughing this morning, he noticed tiny red marks all around his eyes.
I believe the symptoms are linked to Platelet Disorders called Thrombocytopenia

To confirm whether your diagnoses are correct, it is important to consult a medical professional. However, I can help you understand the possible connection between the symptoms you described and thrombocytopenia.

Thrombocytopenia refers to a condition where there is a lower than normal number of platelets in the blood. Platelets play a crucial role in blood clotting, so a decrease in their count can lead to easy bruising and bleeding. This can manifest as bruises appearing all over the body, even without a clear injury. Additionally, tiny red marks around the eyes, known as petechiae, can occur due to spontaneous bleeding in the tiny blood vessels. Coughing could potentially increase the pressure, leading to the appearance of these red marks.

To confirm this hypothesis, it is recommended to seek a medical evaluation. A doctor can perform a physical examination, order blood tests to measure platelet count, and conduct additional investigations, if necessary. They will be able to provide an accurate diagnosis and appropriate treatment options.

Remember, it is essential to consult a healthcare professional for a proper diagnosis and any necessary medical advice.
