Brief Answer:
Diabetic foot.
Detailed Answer:
Hello,
With the back ground of diabetes, there are three possible reasons for foot sore and ulcer.
1. We have ruled out
bone infection by MRI. However it did indicate presence of
joint inflammation (Arthritis). The redness and pain is possible due to inflammation. Consult with your doctor if he can be started on a lose dose steroids to control the inflammation and redness if his blood sugar is under control.
2. Secondly arterial diseases like block in the vessels and arteritis may present as pain, redness and ulcer due to lack of blood and oxygen. To rule out this I advice my patients to undergo Doppler scan to assess the vascular status.
3. Thirdly
nerve damage due to long standing diabetes which we call as
diabetic neuropathy also presents with pain, redness and prone to ulcer due to trivial trauma because of loss of sensation. A
nerve conduction study will help to assess the nerve damage. Medicines like
Gabapentin is prescribed for such problems.
I feel your husband should be investigated further for both arterial disease as well as neuropathy. A good nursing care, tight control of blood sugar and medication will help your husband out of this problem.
Hope the answer helps your.
Let me know if there is any clarification.
