Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
Your description may point to anemia
, low blood pressure and multiple vitamin deficiencies and osteoporosis
It is difficult to point out a single cause at this age online. We need detailed data.
I would advise a detailed evaluation by your doctor for multiple problems that you are facing. vit D and B12 levels may be done.
We need to rule out any bleeding, tumour growths in the differentials.
I hope you are fully satisfied with the guidance I gave.
I would be glad to answer any further queries. May I request you to rate your experience here before you close.
Thank you and Good luck!
