Brief Answer:
?Gastritis with internal blood oozing with Black stools/Under Investigation

Detailed Answer:
Brief Ans-?Gastritis with internal blood oozing with Black stools/Under Investigation

Hi,Ma'm,Thanks for the updated information.
I studied your updates and reviewed with context to the facts of first query of yours.
For your advanced age,stomach discomfort with black stools is a cause of concern for the medical doctors.
This stomach discomfort suggest internal bleeding/oozing from generalized Gastritis or from a Gastric Cancer- growth ulcer.

Hence I would suggest you to get the OGD scopy(Oesophago-Gastro-Duodenoscopy to fix the cause and site the gastric bleeding.
Get the MRCP(Magnetic Resonance Cholangio-Pancreaticography)-to fix any tumor pathology obstructing the ampula of vater or stricture of the distal common bile duct,which may be a cause of the internal bleeding in the middle duodenum.
Other causes of the internal bleed needs to be worked out with Gastro-enterologist,who would get the study of CT barium contrast images.

My Impression-
Based on 3 days history of your black stools with stomach discomfort,though black stool is a cause of worry, You should keep COOL, till the
Gastro-enterologist confirms the diagnosis by a series of tests as explained / indicated above , to rule out any cancerous hidden growth in upper GI upto caecum,which gives black stools.

Medical Treatment Suggested-
It is, only for your advanced age,that these investigations would be needed,if the black stool persists after the Medical treatment as suggested as follows-
Bland liquid Porridge diets
Avoid Spicy,non-veg diet,
Banana Milk shakes x
Plenty of fluids
Tab Zincovit C-/ and B-12 with Folic acid-to recoup the fast healing.
Proton Pump Inhibitors Like-Pantoprazole Tabs 1x 2 times per day x 2 weeks time

You Should Not WORRY-till all the precautionary investigations are done from the experts as the need be,by a team of Gastro-enterologist / and endoscopist/ and Colonoscopist and General Internal Medicine Specialist.

Hope this reply would help you to plan further care of the black stools with stomach discomfort.Hope this reply would help you to plan treatment with your doctors as the need may be,in time to come.

Welcome for any further query in this regard,to be discussed in next session.

If you feel satisfied with this reply,Will appreciate YOU, to write excellent comments on your experience of My services,just to help needy patient visitors like YOU, at the HCM services.

Hi Doctor,
I am a 24 year old woman.
I have acne that was dormant for the last 2 years. It suddenly started reappearing around 2 months back. I started getting a lot of pimples and they left a lot of scars.
I consulted a dermatologist. She prescribed CNN 100 Minocycline tablet once a day, Deriva CMS gel at night and Zincovit tablet in the morning. She also prescribed Sebamed Cleansing foam for face wash.
My query the Deriva CMS gel used to treat acne or for reduction of scars.
Also is the Minocycline tablet an antibiotic? Ive read somewhere that it is usually prescribed for a period of 6 months. Are there any side effects for this medicine? Also what does this medicine do for the skin?

Would appreciate your response.

My 91 year old mother who lives in San Diego, Ca. has been diagnosed with Labyrinthitis. She has seen an audiologist and she prescribed 6 predisone pills per day for 2 weeks. My mother is very sensitive to meds and only weighs 115 pounds. She lives by herself and until now she has been very independent. She is unable to hear out of one of her ears. How long does this last and what do you think her treatment should be.
