I was diagnosed with tension headaches, but could my headache be due to some other disease?

Hi doctor,

Last week, I went to a hospital to find out the cause. Before going to the hospital, I had some symptoms for three days. I searched online about the symptoms and I got a diagnosis of migraine online. But my doctor checked me and told me that I have a tension headache. He gave me two medications Orphenadrine Citrate and Paracetamol for my headache and Benadryl for my night sleeping pattern issue. I have taken these medicines for three days now. These medicines are not enough to deal with my headache and sleeping pattern issues. On day one, after having a checkup I went home. I ate food and it triggered my migraine. I also took some medications as prescribed every six hours. It triggered me to a point where I slept in pain. I woke up in the evening around 8:30 p.m. After eating some food, I took my medications. It took two hours to get some sleep. After sleeping for two hours, I woke up again at 2 a.m. and after that, I could not sleep again. I had fatigue in my whole body and a mild headache different from the previous headache. I spent the whole night with a feeling of nervousness and confusion. On day two, I felt better at 6 a.m. and I tried to eat some food. So I took my medications around 9 a.m.. After taking it, I had a mild headache so I went to bed to sleep. I woke up around 6 pm, I felt hungry and it caused a headache again. After eating, I took some medicines at 9 p.m. I felt sleepy at 11:00 p.m. and it caused stress in me again. I felt so hot outside my body and inside my stomach. After that, I tried to make myself busy to eliminate stress. I tried watching drama. I know that it also triggers me. I spent the whole night watching the drama from 3 a.m. to 8 a.m.. On day three, I was fine and I tried to ride my bike to have some exercise in my body and to make my sleep pattern normal. So I ate my food before riding my bike. I felt normal compared to other days. I stopped doing exercise at 10 a.m.. I took a bath. After that, I started to watch drama again from 11 a.m.. I do not know why my stomach seems to be full. So I continued watching until 2:30 p.m.. I took my lunch even though I still felt full. I did not take my medicines. I do not have a headache but I felt some burning sensation in my stomach. I searched online and it showed me a result of a stomach burn. I want to know whether it is just a tension headache or any other disease. I have seen some information online about migraines along with stomach burn and acid reflux. They are referred to as gastric headaches. What to do now?
