Thanks for posting your query.
Your xray of foot is normal. So it might be soft tissue injury
Ice the affected area and take anti-inflammatory drug like mortin to reduce pain and inflammation. Avoid lifting and rest well.
It generally heals in 7-10 day with rest. If it pesist after that , consult an orthopaedician nearby for a detailed examination. You may get the repeat X-ray of the area affected under his/her guidance.
