If you have started having pain after an injury or fall then fracture should be suspected and you should go for X-ray scans.
Osteoarthritis pain can be suspected with previous injuries to your leg or a chronic developing pain. This can be severe with movements and weight bearing.
Start taking NSAIDs, ice the area and go for X-ray scans.
Follow up with an orthopedician for correlating and diagnosing your condition.
Thank you for response--I will try ice and NSAIDs
I have not been injured but have been working in the yard and garden
Relax for couple of days and take NSAIDs and ice the area.
If the symptoms continue go for scans.
