Feeling Weak And Lack Of Energy. Having Muscle Pain Around Knee And Thigh. Blood Pressure And Sugar Normal. What To Do?

default
Posted on Tue, 25 Jun 2013
Question: Hi there,
For the past week or so i have had a feeling of weakness and lack of energy.
The main symptom seems to be weak jelly like legs and a drain/lack of energy.
I have muscle pain around the knees, back of the knees and also thigh muscles. It feels like i have been to the gym and pulled a muscle but i haven't which is strange.
Occasional i have pins and needles in my right fingers hand back of calfs too, sometimes in the thighs.
I generally feel a lack of energy and its quite worrying. I have checked my blood sugar levels, temperature and blood pressure and they all seem ok.
Any ideas?
Thanks
doctor

Hello XXXXXXX

The most common condition which can cause such a symptom is a viral infection(Flu). But usually you will have fever associated or atleast chills. Fever or chills could have been a week back and what you are suffering from now could be the sequelae.
You definitely have a myositis going which is causing muscle pain and weakness.
Causes of myositis could be Flu, vigorous exercise, autoimmune diseases like Dermatomyositis, Polymyositis, Systemic lupus etc, medicines etc

I would recommend you to get a complete blood count including Hemoglobin, Total counts, Differential counts, Platelet count and ESR. From the counts usually doctors get a clue whether an infection is going on.
Anemia also can cause feeling of lethargy and tiredness.

Hope I have answered your query. If you have any further questions I will be happy to help.
Take care
