Hello,
The swelling on your hand and joints of index finger and thumb is likely due to strenuous use of your hand for your work. It is possible that you are doing a lot of work lately.
Or something you got hit with and it went unnoticed. Chances of it because of
tetanus are very less as the organism resides mainly in the soil.
Whenever a patient comes to me with such complaints of swelling and
numbness along with history and examination of the swollen area, if required I suggest him to get an X-ray of hand done as well as some other tests.
Also, I advise him to take rest for few days. For you, I suggest you should see a doctor and follow his advice regarding it.
It is important to find out the underlying cause for this so that it can be treated properly.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Manisha Auradkar, General & Family Physician
