Hello,
Thanks for the query to H.C.M. Forum.
Pain in the finger nail that too from last,
Two months,
Localized pain at one point,
Excruciating pain,
Diabetic family history,
No
redness,
No swelling ,
No cuts or
injury.
Pain may be in the bone of finger,
May be due to infection of bone of finger.
As there is history of
diabetes so please don't take it lightly.
Few things are necessary for diagnosis as,
X ray of effected part,
Age is also important.
Blood examination for sugar, E S R ( if very high indicator of some chronic infection).
So consult a physician and get in above mentioned examination so that as early as possible diagnosis could be established.
Hope I have answered your query.
If further any question I will be happy to help.
Good luck.
Dr. HET.
