Hi there. These headaches could be migraines or tension headaches, sinus headaches radiating to the ear, headache usually front of head, on one or both the sides of temples along with nausea, vomiting, irritability, low blood pressure, sensitivity to lights, sound, etc. aura associated with migraines could include blind spots, blindness in half of your visual field, paresthesia, weakness or visual hallucinations. Your mother’s vision needs detailed testing by an ophthalmologist. Hypertension and hypotension need to be checked. An MRI brain is warranted to rule out any intracranial lesion particularly aneurysm and MRI spine for ruling out cervical spondylosis and degenerative disc disease. Temporal tendinitis mimics migraines including TMJ pain temporal headaches, tooth sensitivity, neck and shoulder pain. Treatment includes injecting local anesthetics and other medicines, moist heat muscle relaxants and NSAIDs along with physiotherapy. Multiple sclerosis would also need to be excluded. Treatment for migraines include drugs that prevent the attack like anti convulsants and drugs which treat an attack like triptans, ergots etc your queries should pertain to all these possible differential diagnoses. Trigeminal neuralgia needs to be considered. Hope this helps. Take care.

I am not a physician so take what I say with a grain of salt, but a desire to help and some understanding of the neck. I have never heard of popping or bubbling in the head, but can only think it is a feeling or pressure that is transferred into a sound in the brain or head. There was a study done in Detroit at one of the hospitals in which the 45% of the people suffering migraines were able to get relief from what you might call massage, but was more of a posture change. There is a head forward posture that most of us are guilty of and after a while it forces the brain-stem/spine to press against the opening of the base of the skull. This will cause severe pain in a lot of people which translates into the diagnosis of a migraine.
Sometimes just applying traction to the head while lying on their back will relieve some of the pressure. I can accomplish this by cupping the head with my palms and with my fingers on the underside of the skull where it meets the neck; I'll pull gently and hold for a minute or two. Depending on the age or fragility of the client’s neck will determine how much pull I apply or whether I do it all. (With age and bone strength being a factor)
With the patient lying on their back, prone position, massage the muscles of neck and around the base of the skull. There are a lot of small muscles traveling up and down the neck along the spine. Once the neck muscles are have been massaged, apply pressure to the last 2 vertebrae so they are moving up. Holding the skull stationary or slightly tilting it so the base of the skull has downward pressure. This in effect applies opposite pressure that the client may have been generating by doing their everyday routines, (watching tv in bed with too many pillows, hunched over a computer screen or a book.)
I don't know if what I explained will help, but this is something I would have investigated, since stress may be some part of the actual culprit, tightening of the neck muscles are right in line with this area. Good Luck.
