What Causes Sharp Pain In Fingers?
Needs elaborate laboratory evaluation to establish the cause
Detailed Answer:
Hello ma'am and welcome.
Thank you for writing to us.
I have gone through your query with diligence and would like you to know that I am here to help. Burning sensation in the knuckle(s) is usually related to some chronic and systemic conditions, but I cannot use it to establish a diagnosis as all such symptoms need elaborate laboratory evaluation, so please do try and consult a doctor for a more elaborate evaluation ma'am.
But I shall go ahead and list as many conditions that come to my mind that can cause such a presentation:
+Diabetes
+Systemic lupus erythematosus (SLE)
+Smoking
+Raynaud's disease
+Contracture (Duputyren's)
+Polymyositis
and a few others.
The aching knees do add to possibilities like SLE, diabetes, etc. But then again, this would be an assumption as it requires laboratory backing up ma'am.
I hope you find my response helpful. Please feel free to write back to me for any further clarifications, I am always here to help.
Best wishes.
