What Does My MRI Test Result For Headache Indicate?

Doctor, I don’t know how much accurate the online consultancy procedure can be but I would like to hear from you genuine suggestions and opinions.I get headaches quite often once in two weeks or 3 times a month. I visited a neurologist and he prescribed the following medicines:clotan 200mg ( incase I get headaches )Betacap plus 5 ( morning and night)Valparin (morning and night)He said that it was a type of migraine the MRI and MRV showed that there is “cyte retention in right Maxillary”, everything else seems normal. But my headaches are on the left side of my head.I remember getting headaches on the right side of my head and they have been very bad but in the past few years it might have occurred for 4-5 times only.The signs of my head aches on the left side of my head are as follows:acute pain in the back of neck and brain.( I can point where it pains)acute pain on the left side of my forehead .( I can point where it pains)it occurs in the evenings only 6-11 pm …but the head feels heavy the whole day.Medicines usually don’t help it starts slow reaches peak at 6-7 and lasts for an hour or so 7-8 and then reduces. Sometime it continues into the night which is very bad.I had not visited any doctor on headaches, but recently I began to get thunder clap headaches which lasted for 15-30 minutes till one hour for the past few weeks. It was then when I visited the doctor.With these medicines the thunderclap headaches are not there anymore.They use to occur usually while exercising and after 2-3 minutes talks over the phone. And also they were on the left side only.I have had headaches for many years.I hope this information is enough for you to make a consultation.Thank you for your time and effort. Medrik Minassian
