It could be a number of things. You haven't given us enough info. to make a "proper diagnosis". Was your illness just a head cold or something more serious? Do you eat shortly before you workout or do you workout on an empty stomach? Have you been getting the proper number of calories each day? Do you have any underlying medical conditions; diabetes or hypoglycemia? Also, if we've been ill, it sometimes takes our bodies a couble of weeks to recover completely. If the answer is not as simple as "Yes, I've been working out on an empty stomach and just eating 750 cal. /day", a call to your doctor to bounce the question off him would be a good idea.
SparkPeople has an article on foods to eat before and after workouts, the timing of the meals etc. Carbs are good before a work out.
Also, I almost forgot, are you hydrating yourself. Dehydration can affect your muscles. You can be dehydrated and not know it. There is a good SparkPeople article on that topic, as well. Just "google" it on the SP site.
I hope this helps a little.
