User :   I have a lower left leg amputation (for 35yrs) I get blind boil type infections on the pressure ares of my stump. Anti biotics usually clear them but they often reoccur and have to lanced. What causes them and can I do anything to prevent them
Doctor :   Hi
Doctor :   let me read ur query
Doctor :   proper hygiene and protective gear for the leg stump will help in your case
Doctor :   improper healing or presence of any infection under the skin will have to be ruled out as well.
User :   I am very clean and hygenic with both my stump and silicone prosthetic sheath and disinfect them evry evening before bed
Doctor :   that is good
User :   I lost my leg 35 year ago and have a very healthy stump and am very active.
Doctor :   Do u have any pain, discharge, etc from the site ?
User :   no not at all
User :   Pain from the boils site when it is under presuure from my prosthesis
Doctor :   Do you have any medical conditions like diabetes etc ?
User :   No not at all.
Doctor :   may i know the reason for the amputation ?
User :   Traumatic amputation from a landmine explosion
Doctor :   ok, sorry to know that
User :   No problem I was there voluntarily ;o))
Doctor :   the cause for your issues here , could be due to infection in the skin follicles or any underlying infection in the underlying bone stump
User :   how can I prevent them?
Doctor :   A X ray of the bone could give an idea to check put if you have such a infection in the bone
Doctor :   also a course of antibiotics will be good to treat the infection as well
User :   The infection is in the soft tissue and occurs in different palces, once I have got rid of the offending one.
Doctor :   also a culture sensitivity , will help to decide the antibiotic to be used as well
User :   As I said earlier, anti biotics clear them but they seem to reoccur and have to be lanced.
User :   Done, and we are using an effective anti biotic
Doctor :   this seems to be recurrent abscesses
User :   yes, but in different palves.
Doctor :   Have u had a culture sensitivity of the pus or secretions from the boils ?
Doctor :   you may need a prolonged course of antibiotics, to completely remove the infection
User :   Yes and they didn't produce anything out of the ordinary except the infection. I cannot remeber what the infection was
Doctor :   incomplete treatment could be the reason for incomplete removal of infection
Doctor :   and this in turn causes recurrance of boils
User :   I have been on very lengthy anti biotic courses to ensure that the treat was complete and effective.
Doctor :   prophylactic application of topical antibiotic ointments will help
User :   What causes them?
Doctor :   Are you there ?
Doctor :   Persisting infection in the hair follicles of the amputated limb is the cause
User :   particularly
User :   How can I prevent them?
Doctor :   skin microbes like staph epidermidis could be the cause
Doctor :   Novobiocin ointment would help here
User :   Will that help prevent them?
Doctor :   yes
User :   Thanks Dr is there anything else that I can do?
Doctor :   I guess you are doing all that including maintaining good hygiene already
User :   Thanks very much, will give it a try. Bye.
Doctor :   A repeat culture sensitivity will be helpful to guide the systemic antibiotic to be used
Doctor :   Thanks and bye for now
