Thank you all for your help.

Need advise. Took a dose of Natrum Mur 30C yesterday morning. Later in the day yesterday, my legs were aching (old recurring symptom). Today, I am having fever 99.3deg F. This fever is also a an old recurring problem.

With this reaction does it confirm the remedy? Congestion is about the same. Energy level is very down. Should we just wait for the fever to go away without taking anything else or should I take a dose of Natrum Mur 200C?

Thanks
