Complex Regional Pain Syndrome (CRPS): This condition is characterized by chronic pain, swelling, and changes in skin temperature and color, often following a traumatic injury. The patient's symptoms of acute exhaustion, pain (6/10) when lifting, and swelling on the dorsum of the hand are consistent with CRPS.

Tendinitis or Tenosynovitis: Inflammation of the tendons or tendon sheaths can cause pain and swelling, especially with activities like lifting. The history of trauma and the specific location of pain and swelling make this a plausible diagnosis.
Ganglion Cyst: A common condition where a lump forms under the skin, often on the wrist or hand, which can cause pain and swelling. The "particular looking dots" on the dorsum of the hand could be suggestive of a ganglion cyst.
Repetitive Strain Injury: Although the initial trauma has healed, repetitive activities could lead to strain injuries, causing pain and swelling, especially if the patient has returned to normal activities without adequate rehabilitation.

Osteomyelitis or Septic Arthritis: Although less likely given that the initial injuries have healed, it's crucial not to miss infections of the bone or joint, as they can be severe and require immediate treatment. Symptoms can include pain, swelling, and systemic signs of infection.
Compartment Syndrome: A condition where pressure within the muscles builds to dangerous levels, which can occur after trauma. It's a medical emergency that requires prompt diagnosis and treatment to prevent permanent damage.

Sarcoidosis: A condition that can cause inflammation and swelling in various parts of the body, including the hands. While rare, it could potentially explain the swelling and pain if other diagnoses are ruled out.
Erythromelalgia: A disorder that causes burning pain, heat, and redness in the hands and feet. It's less common and might be considered if other diagnoses do not fit the patient's symptoms.
