Heel pain is a common foot problem and has a number of possible causes. The most common cause is plantar fasciitis, which is inflammation where the plantar fascia attaches to the heel bone. The plantar fascia is a thick band of connective tissue that spans the sole of the foot and provides shock absorption while walking.
Might be useful to mention where you earned these degrees but generally in the US Bachelors = undergraduate and Masters = graduate. Post-graduate is kind of an umbrella term that might mean Masters/PhD but also might mean professional certification or maybe even something like continuing education.
Undergraduate education is the post-secondary education previous to the postgraduate education. It includes all the academic programs up to the level of a bachelor's degree.he South African system usually has a three-year undergraduate bachelor's degree, with two or three majors. (There are exceptions, such as the medical qualification (MBChB), which is six years.) A fourth year, known as an Honours year, is considered a post-graduate degree.
