Always collect the information about a document at the same time you download the image. You can't be sure that the collection will be online if you go back to look at it later -- over time, commercial websites may lose the right to host the database.
Without the information that identifies the image and where it came from, you can't evaluate the document properly or evaluate completely the information it contains.
In her book Evidence Explained (page 8 of the 3rd revised edition), Elizabeth Shown Mills emphasizes how important this is. She says:
Consulting maps and gazetteers from the period of your document can also help in your analysis. Hudson City, New Jersey is now part of Jersey City, in Hudson County, directly across the Hudson River from Manhattan.

The Source information includes the following:
Publication Title: New York, Civil War Muster Roll Abstracts, 1861-1900
Content Source: New York State Archives
Fold3 Publication Year: 2014
Short Description: Abstracts from original muster rolls for
New York State infantry units involved in the Civil War. 1861-1900
The main page on fold3 for this collection says:
The records have personal enlistment information and military service,
as well as regiment engagements. The personal record and unit
information makes the collection valuable to anyone with New York
ancestors in the Civil War era. The beginning of each regiment record
has information on the regiment including the commanding officers. In
a few of the abstracts, a detailed history of the unit also appears.
The regiment's information will have to be browsed for or searched by
regiment.
Gather information from the repository that holds the record
The New York State Archives' page on Civil War Service Abstracts says:
Abstracts of muster rolls of NYS Volunteer Units that served during
the Civil War (Series 13775) are available on self-service microfilm.
The Archives does NOT have original muster rolls.
Content varies, but abstracts generally provide: enlistment date; age;
place of enlistment and for how long; date mustered in; grade;
company; regiment; date left organization; reason for leaving (killed,
discharged, deserted, etc.); in what grade; and "remarks."
"Remarks" may or may not include service details (reduced to private,
deserted, temporarily assigned to special duty, etc.). Sometimes, but
not always, physical descriptors (height, eye color) are present.
Names of soldiers’ parents or spouses are not present.
Offsite researchers may print out and mail in a War Service Records
Request Form to purchase a photocopy of an abstract.
Note that the New York State Archives doesn't have the original muster rolls from which this information was abstracted. You will have to locate other sources about the New York State Volunteers in different repositories to get more information.

Further research will be required before you can locate medical records about this soldier, since this record gives you no help -- there is no hospital name or date the soldier was admitted. Medical records are not likely to be online, and they are likely to be arranged by medical facility and arranged chronologically.
