after high pressure injection injury?

Back 5

4. Time to treatment [ > 10 Hrs worse ]

Front 6

Which is incorrect regarding High pressure

injection injuries?

2. No tenderness at / around site several hours after injection , suggests no significant injection has occurred.
3. Surgery is necessary when tenderness noted distal and proximal to

injection site.
4. High pressure water injections are worse than paint injection.
5. A pressure of > 7000psi has a 100% amputation rate.
