Thanks for posting your query.
If you are getting an adequate pain relief with this dose then you can continue with it. In case the pain relief is lesser then increase the dose to 400 or 600 thrice a day.
You can also do a hot fomentation in the area to relieve pain and stiffness
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Wishing you good health.
