Hi,
Noted the history related to your husband having pain in abdomen, constipation, vomiting after taking
Magnesium Citrate, diagnosed a Shingles but no painkillers helped.
Diagnosis of Shingles before appearance of typical rash may take 5 days to and the pain may not respond to classical pain medicines.
Needs antiviral and strong painkillers for pain of nerve origin.
The history and distribution is classical, the pain is superficial and in the skin and not in the abdomen.
Hence I would advise you the following:
Consult your Doctor again or
consult a General Surgeon for proper clinical evaluation, examination and go for investigations like
Ultrasonography of abdomen.
CT scan if required.
Tests of blood, urine and stool.
Since there is vomiting after the laxative, it may be better to change over to another
stool softener or laxative.
All this lead to a proper diagnosis and also see for
appendicitis, colitis,
and so on.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
