Glandular fever must take a toll on the body that the shock from it causes physical anxiety. I get physical anxiety and Ive had another sensory issue 5 years ago. It was globus hysteria(one name for it) I was fasting, not sleeping well, stressed and I'd always had anxiety without addressing it. It was a sensation of hair in my mouth, tounge and throat, can be like a intrusion type of feeling in the throat for others but it's a pyhschological sensation either way. Took meds to calm me down, took few months and it's never occurred 5 years later. Now I'm getting ms type sensations in my hands feet for 2 months. Seen a neuro, mri brain and spine, clinical test also, he pricks the nerves around body, eye test, movement. They say it's not ms, so now I've been prescribed a type of low dose medication to calm down my anxiety from my gp for the first time and resting, it's a lot better. Can be random but it's 100% physical eg if I don't eat enough during the day it gets worse. I believe physical anxiety is the culprit for sensory issues. Can happen to anyone and I personally know similar cases with healthy non anxiety sufferers who devolop sensory issues for a few months due to a traumatic experience. I have tried a few anxiety meds that my gp prescribed over 5 years, they never work for me. I'm a physical anxiety sufferer, it's from a genetic disorder of the bodies connective tissue, called edhlers danlos syndrome. That's why most type of anxiety meds don't work for me because it's not so much pyhscogical. I get anxiety all day everyday but I can function because I think it's adrenaline induced because it's physical. In conclusion when the body is run down or gets a shock from the immune system, stress, poor diet, fatigue or more commonly in combination can cause sensory issues. I was convinced of ms. If anyone reads this, the neuro consult is always the right choice. Do not self diagnose, do not Google. Do not Fb group every ms group. Its a never ending anxiety roller-coaster. You need assurance, go get it. Ask to see a specialist and get a 2nd opinion if needed.
