The question assumes the bottom of the heel is the usual place for pain. The definitions below do not limit pain to one surface.
The answer is yes
MedlinePlus defines heel pain as pain or discomfort located at the back, bottom (plantar surface), or sides of the heel. The back is listed first, so your location is covered by the definition itself.
What the back-of-heel wording points to
AAOS OrthoInfo says people who have pain behind their heel may have inflamed the area where the Achilles tendon inserts onto the heel bone. The word "may" matters. It names a possibility to bring to an exam and does not diagnose you from a description.
The plantar fasciitis review from the AAFP, titled Evidence-Based Review of Diagnosis and Therapy, covers the bottom-of-heel condition that most people expect. For the other locations, see MedlinePlus on heel injuries and disorders, the AAOS page on heel pain, and the Cleveland Clinic page on heel bursitis.
What to confirm, and with whom
Tell your foot doctor exactly where it hurts: back, bottom or side, and what you were doing when it started. A vague "heel pain" gives the clinician less to work with than a specific spot. Readers in Itasca should expect to be asked to point to the spot.
The clause readers tend to skip
"Located at the back, bottom, or sides" is one definition with three places in it. A search that returns only the bottom-of-heel condition has answered a narrower question than the one you asked.
