Swelling is also due to accumulation of that extravasation fluid.Tratment is ice fomentation, strict limb elevation. Tab diclofenac 50 mg twice a day is for pain relief. Tab chymoral forte twice a day is for reduction of swelling. It has to be taken before meals. This will resolve in few days.Hope I have answered your query. Let me know if I can assist you further.Regards,Dr. Jayesh Vaza </s>
