Yes,but only if it is just soreness and you have no temperature or foul discharge.
The problem with 3rd degree is that affects so many layers in your perineum and vagina involving outer skin,muscles and nerves and it takes time to heal.It also depends how the stiches were applied,they may be to tight and nake you feel like there is pulling sensation.
If you feel otherwise OK,it should be more comfortable in couple of weeks.
