The lump you are feeling is likely an Injection Site Granuloma or a Hematoma (a small collection of blood or fluid). This occurs when the medication is not absorbed quickly into the muscle or leaks into the surrounding fatty tissue, causing a localized inflammatory reaction.
To answer your concerns:
Is it curable with ice? Ice is most effective in the first 24–48 hours to reduce swelling. Since it has been 10 days, warm compresses (using a warm water bag) for 10–15 minutes, 3 times a day, are now more effective to help increase blood flow and dissolve the lump.
Will it cause severe damage? In most cases, no. These lumps are usually "sterile" (not infected) and resolve slowly on their own over a few weeks.
Pain while jumping/walking: Since you have a metatarsal fracture, you should strictly avoid jumping or putting undue stress on either leg, as this can aggravate the injection site and delay fracture healing.
Recommendations:
Topical Application: You can apply a heparin-based ointment (like Thrombophob gel) or a localized anti-inflammatory gel over the lump twice daily without massaging it.
Monitor for Infection: If the lump becomes hot to the touch, very red, or if you develop a fever, it may indicate an abscess (infection). In that case, you must see a doctor for a physical exam and possible antibiotics.
Rest: Focus on your upcoming exams and keep the leg elevated. The lump should gradually shrink.
Disclaimer: This is a clinical opinion based on your description. If the pain increases or the lump grows in size despite warm compresses, please have it clinically examined.
