A BHMS doctor learn homeopathy and usually can’t do MS degree. MS is for surgery and teach how to do operations. BHMS doctors learn homeopathic medicine, which use natural things to help body heal.
BHMS doctors know lot about medicine and patient care, but MS need special training in surgery like general surgery, bone surgery, brain surgery, heart surgery and more. BHMS don’t learn these in college.
So, BHMS doctors don’t usually do MS, but they can learn more and become better in homeopathy with other courses and certificates.
