Well, it certainly could be anxiety- Going with the axiom that you should think of horses and not zebras when you hear hoofbeats.
If you're not too burned out on going to the doctor, I might suggest going again, mentioning the earlier diagnosis of anxiety, and ask your doctor to rule out any neck and spinal problems for you own sense of well-being.
I tend to get strong tension headaches, myself, and these are often accompanied by soreness in my neck- it's very possible to actually get some swelling and inflammation around the tendons in your neck and around the periphery of the trapezius muscle where it joins the bone of your skull- the occipital bone. So long as there's no physical issues with your spine and bone structure, the potential for relief through pain management and anxiety management is very good.
I get a very similar feeling in my neck at times, which has been diagnosed as severe tension because I apparently "carry" most of my stress in the neck and shoulder area. My arthritis also plays a part in the stiffness, as it causes inflamation which can result in the swelling of tendons, muscles and ligaments and these can produce a sort of clicking or snapping sound when rotating your neck. (Hurts like hell, doesn't it?)
You say you have headaches, which are relieved by massage, as is the tension. This just lends more credence to the stress theory. Massage will NOT ease the pain of a brain tumor. I do NOT want you to Google "brain tumors!" (The monkey's will be watching!)
I'm just a little unsure if you had the MRI when all of these symptoms were present. If they were, you can certainly rule out the brain tumor. That would have stuck out like a sore thumb when the picture was "read."
Virtually every symptom you described can be attributed to anxiety/panic, which you said you WERE diagnosed with. What tests did your doctor run to rule out organic reasons for these symptoms? If she ruled out everything and anxiety/panic was the only thing left on the table, what course of treatment did she put you on? Did you get into therapy to help you find the root cause of your panic? Medication is great for the nasty symptoms of anxiety, but it only masks those symptoms, it doesn't do anything to help you find the cause which will lead to recovery.
If it's been a year since you last saw your doctor and you've been suffering with this arrary of symptoms, I'd say it's time to go back and have a thorough follow up exam and a long heart to heart about your anxiety. I hope you also talk with her about seeing a therapist.
Anxiety and panic are horrible conditions to try and live with, but there is so much help out there, nobody has to suffer in silence any longer.
Please get some help. You're too young to have THIS monkey on your back.
check ur tmj
dw im going through the same thing after i dislocated my arm
woke up that morning with psin in my head so the dr shoved me on zoloft
day 3 and the pains gone but i feel abit dizzy
"Numbness in one side of my head/face (comes and goes)"
Sounds like it could be Bell's Palsy cranial nerve VII.
I used to get this. Gone with antibiotics. The cause was Lyme disease.
To me, your symptoms look more like something infectious such as Lyme disease and/or co-infections or ME/CFS. Both these illnesses can be the root cause of extremely severe anxiety. I saw about 20-30 doctors and specialists and never gave up until the cause was found. Many would dismiss me. Doctors would "rule things out" and give me "peace of mind", but the whole time they were just running the wrong tests.
Doctors confuse these conditions with depression/anxiety since depression or anxiety can be a major symptom. Because of the NHS and because many doctors are unaware of or disregard these diseases, it is hard to get a proper diagnosis and help in the UK.
By the way, I had every symptom you had minus the numbness across the chest.
I used to have a symptom list that covered the front and back of a piece of binder paper.
And while I am not a doctor, your symptoms do not look like a tumor.
Believe me, I was so persistent that I was scanned head to toe with MRIs and CT scans.
If it's one of the conditions I mentioned, depending on the day/week/month of the scan, an MRI could show abnormalities of the white matter of the brain, but most likely not a tumor (unless you were born with a non-malignant one).
You haven't mentioned high blood pressure but something your doctor could rule out would be a pheochromocytoma.
Rare adrenal tumor, but they are screening for it more now (at least in the United States). It can be ruled out with a simple blood test that is extremely accurate.
Most likely that's not it, but you never know.
Lyme disease is transmitted by blacklegged ticks. So unless there was exposure to that typical tick it probably isn't lyme disease.
