Cervical spondylosis. Uterus fybroids.

My sis (female/ 40 yrs/ vegetarian/teetotaler) had headache on the top of her neck between ears for few months (near the hairline at the back). She was taking normal pain killers. Recently she felt dizzy and almost passed out for few hours with severe pain in neck and vomiting (though conscious). She was absolutely ok the previous day but woke up with severe dizziness the next day. The doctor initially suggested Sumo, Vertin 8, n Vomikind along with xray. The medicines reduced pain n dizziness. Xray suggested Cervical spondylosis and refered to ortho. There is no pain in shoulders, hands nor any problem in walking. However there is pain between the eyebrows (she uses specs). She relies on home medication and doesn't want to go to ortho until absolutely necessary. Can someone plz suggest something..? How long and how often can she take the above medicines (since they are working well).? She also takes thyronorm 50 since 4-5 years and 6 yrs back had surgery for uterus fybroids.
