It's fine. Stay within reason, and work on meditations and practices that are more mind or soul centric, as opposed to body centric. Don't try to stretch your limits, and generally take it easy until you are well again. Makes sense, yes? And I didn't have to use any tough-to-pronounce foreign words.
As others have said, it can be that you've fallen sick because you have started practicing again. Since it is rather common for the body to become weak or fatigued when the mind or soul have been pushed to their limit, take this into account. Have you tried anything particularly difficult or exhausting? Avoid things like that when just starting practice, and do your best to safely expand your limits rather than overstep them.
