Brief Answer:
Doesn't Seem to be an infection problem
Detailed Answer:
Hello
Welcome to Health Care Magic.
My name is Dr Muhammad Ahmad & i will look into your problem.
I have gone through your query and would try to help you in the best possible way.
OUR OPINION:
Your father went through Back surgery it definitely would have been done because of pain or movement issue,it got infected or he got infected from some other source not related to surgery and he again had to go to hospital,where is Staph infection was treated.
In My opinion the pain and symptoms he has are not suggestive of a complication or an ongoing staph infection unless there is high grade
fever general body aches shivering loss of appetite skin rashes or related symptoms of which you mentioned nothing.
So My opinion this issue relates to your father's back, may be the surgery didn't cure what it should have or may be a new things has appeared.
If i were your doctor after ruling out staph infection (as you are concerned about it) through blood work and culture i would have put all my focus on his orthopedic issues,if its a structure touching his
nerve or a disc compressing on or is it
neuralgia of some sort or a
muscular pain,
For that these days we have got so many state of the art diagnostic modalities
like MRI
Dopplers
Nerve conduction studies
Radio graphs
Ct scans
Bone tagging
and much more
WHAT TO DO NOW:
(1) Talk to the doctor who operated/Orthopedic consult:
i would suggest you to discuss all the options with your doctor specially the one who operated on him ,if there is any complication of surgery or the surgery didn't work or is there any new problem arising , an Orthopedic consult and diagnosis seems to be the key in this problem.
(2) Pain clinic: There are specialized pain clinics which can use different methods to relieve pain these clinics can be found specially in association with cancer hospitals and clinics.And here again i will say that Pain can be managed better if diagnosis is made.
(3) Support you father mentally dont let him lose hope
(4)Physiotherapy: This also is a very developed science these days and can help patients in re-hab.
CONCLUSION: A good diagnosis first.
Hope I have answered your query. If you have any further questions I will be happy to help if not then don't forget to close the discussion and rate it.
Wishing you good health !!
