The clinical presentation of thromboembolism can vary widely. In cases of DVT, patients may experience swelling, pain, and redness in the affected limb. Pulmonary embolism may present with sudden shortness of breath, chest pain, and hemoptysis. In renal vein thrombosis, a specific form of thromboembolism associated with nephrotic syndrome, patients may exhibit flank pain, hematuria, and worsening renal function.
