Thank you for asking Healthcare majic.
My name is Dr Ehsan Ullah &
I have gone through your query.
you have mentioned about knee sprained which you didn't care properly n timely,
now
it has pain , swelling and numbness
along with walking difficulty
knee joint is quite complex and has important nerves and vessels located in it specially on the back side of the joint.
The swelling occurs when there is damage to the tissues in the knee so this swelling can be just an inflammatory swelling as a result of tissue response to trauma or it can be a collection of fluids resulting from the damage to the structures e.g vessels
while
Numbness occurs when there is damage to the nerve or there is some vascular compromise
for the pain relief , you can use
ibuprofen 400
(The recommended dosage of
Brufen is 1200-1800 mg daily in divided doses)
Rest and application of
knee brace will reduce the swelling
meanwhile
you will have to visit your physician for some work up to role out cause of this swelling and numbness in the form of radioghaphs,
ultrasonography and
nerve conduction study after detailed history and clinical assessment.
Hope this may help you. Let me know if anything not clear.
Thanks.
