Hi,
Although I could not make out what a "neutromatta" in
ultrasound means (may be a typing error), pain and swelling there indicates a focus of inflammation. This can be from a local infection,
injury to bones, ligaments or an outgrowth from them. As the sonologist suggested,
MRI is needed to exactly define the tissue of origin and type of the lesion- which is necessary for orthopedist to plan the management.
Since it is an acute painful condition, few days off the job is unavoidable. Otherwise, this will further worsen the condition and delay recovery. Give rest to foot, keep it elevated, and take analgesics like
ibuprofen for pain relief till the issue is sorted out.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Muhammed Aslam T. K., Pediatrician
