He has treated his patients like this and his only concern during the office visit is the patient and the issues that pertain to their health.
The adrenals are two small glands that sit one on top of each kidney. These tiny glands are related to stress and our "fight or flight" response. The fight or flight response is designed to keep us alive at all costs! This stress response was modeled to keep energy flowing to the muscles and the brain for pure basic survival.
It is an issue when it interrupts your routine and daily life. Fibromyalgia Syndrome (FMS) and Chronic Fatigue Syndrome (CFS) are medical illnesses that share many common features. Everyday fatigue may exhibit many of the same features and may actually be an undiagnosed FMS or CFS. I have had patients that were so tired that they couldn't get off the couch for months on end.
Visit Dr DeCosmo in St Petersburg to see if you qualify for the Florida Medical Cannabis Program. The Florida Compassionate Medical Cannabis Act of 2014 / Amendment 2 allows Florida state certified doctors to order medical cannabis derivative products for patients with a qualifying medical condition.
This is all well and good as long as your body can absorb the supplements that you take in. What happens if we get a poor non-absorbable form of vitamin or, worse yet, our stomach is not functioning properly and cannot absorb what we put into it! This is when intravenous vitamin therapy does a great job!

He was the first person in four years to dignify me by listening to me and treating my condition. A very special physician and human being.

Very nice guy.
Milked me for over 500 dollars and then said it would be another 250 for my mmj card . Just a bit of a rip of, but very pleasant while he did surgery on my wallet.

Spends a lot of time with you. Takes you OFF medications rather than putting you ON meds. Great bedside manner, too! - Beverly Sweetman
