Thanks for writing your query
After going through your query the chances of screw rubbing against muscle are minimal as the screws are in flush with plate. For your satisfaction you may get an x ray
The plate and screws are not removed usually until and unless they create a problem and that too after a period of 18 -24 months after the surgery.
For now my advice would be take a break from exercise for few days (7-10).Take ibuprofen
to reduce pain and do ice fomentation along with-
1. Gradually increase exercises preferably on weekly basis and to be followed by ice fomentation.
2. Take balanced diet rich in calcium (1000mg/day) and vitamin (1000 i.u. /day) along with vitaminB12, B6.Vitamin D is available in weekly dose pattern as well as injection, just talk to your local doctor.
Hope this information helps you.
Take care and I shall be glad to answer any further query.
