On 21st july i had snapping tricep surgery. should i still be feeling the tricep snapping slightly? is it ok to lift weights with it snapping?

Ask your surgeon: Only your surgeon has the answers to these questions. Don't be afraid to ask!

Depends: Unfortunately, you should follow-up with your surgeon to determine activity level. If the tricep has healed well, there should be no problem. If the tricep is not healed, doing more can cause damage and you may have to undergo another surgery to fix the "new" damage.
