Thats tough to say because everyone is different. Taking extended time off of lifting/training is mandatory for hard training athletes. Giving the body time to reach a total heal will do wonders for your performance. Sometimes a week will suit you well, however sometimes it can take over double that. I just got done taking about 20 days off of lifting completely. I even cut out most cardio!! :/ It was tough, but well worth it. I am back to full strength and my energy levels are through the roof just ten days after starting back. You may want to give it a few more days and see if your body responds.. just a suggestion though.
