Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that the symptoms of pus discharge near the cuticle of nail along with soreness and pain and bruising seems to be due to infection in the area of skin near the nail and occurs commonly due to causes like bacterial or
fungal infection..
This condition is known as
PARONYCHIA..
It can occur due to conditions like traumatic
injury to the side of the nail like while washing clothes or dishwashing, injury while cutting nail, nail biting habit , overzealous manicure etc..
As you have only one kidney so the entire renal function is dependant on it therefore medication especially antibiotics and painkillers has to be taken with great caution..
I would therefore suggest you to
consult a General Surgeon and get evaluated and a thorough clinical evaluation is generally sufficient for diagnosis..
You can be advised to apply a combination of
steroid, antibiotic and antifungal ointment over it..
If it is painful topical application of numbing ointment and taking
tylenol can relieve..
Do cool compresses over it..
If the lump is large and painful
Incision and drainage followed by a course of antibiotics and painkillers will relieve..
Hope this information helps..
Thanks and regards.
