Question: Fatigue responsive to Doxycycline hyclate

 mincy - Tue Aug 10, 2010 7:13 pm

Hi, I have been suffering from a fatigue for about 3 months now which has steadily gotten worse, wake up feeling exhausted (mornings are worst), headaches, joint and muscle pain, lack of concentration etc.

I did have a minor case of sinusitis prior to this which I didn't treat, and also have a likely case of erythromelalgia on my feet (not sure if related).

I went to a doctor who gave me a 10 day course of Doxycycline hyclate and within a few days I noticed considerable improvement, not 100% but better. As soon as I finished the course within 3 days I was back to feeling very bad.

I was wondering if this information will help with a diagnosis or if I should just get back on antibiotics regardless and see what happens?

Any ideas would be greatly appreciated.

User avatar Hello,The symptoms of fatigue,body pain,arthralgias,malasise could all be a part of lyme disease caused by tick bites.Early localized lesion after a tick bire is known as erythema migrans,a skin rash.After this it is a protracted problem recognized late with arthritis.
Why should one think of lyme in your case?The responseto doxycycline which is prompt in this condition.
Serologic testing is indicated if there is a history of bite or suspicion.Do consult your doctor,and my answer is only a possiblity and nothing more than a speculation.
Best wishes.
