A CT scan is typically necessary only if your doctor suspects complex bone fractures or joint damage that standard X-rays cannot clearly show. Regarding the "blood clot," it is important to clarify if it is a superficial bruise (hematoma) or a deep vein clot. For a localized bruise, your current prescription of diclofenac and serratiopeptidase, combined with rest, ice, and elevation, is highly effective. However, if it is a vascular clot, you may require specific blood thinners (anticoagulants) and an ultrasound. Please consult your physician to confirm the exact nature of the clot and ensure your treatment plan is fully tailored to your recovery.
