Do not underestimate anxiety. For the past two+ months, I've been dealing with an assortment of symptoms that had me seeing my PCP and multiple neurologists to diagnose the cause of what was thought to be some extreme form of neuropathy with other abnormal nerve behaviors.
Severity varied from day-to-day, but during the worst flare ups, I had tingling and numbness to some extent from head to toe, chills, frequent urination, lightheadedness, twitching, unsteadiness while on my feet, hunger, nausea, tiredness, general malaise, and at the worst of times, suicidal thoughts (because who wants to live with all of that). Exercise or even common household activities seemed to exacerbate my symptoms. The only time I felt somewhat normal was while sleeping, and I probably spent at least 50% of my time in bed. I had several blood tests, brain MRI, ultrasounds, and physical examinations. Everything has been coming back as normal.
While researching some meds that had been prescribed, I came to the conclusion that we were chasing the wrong cause, and started looking into anxiety. Once I was able to plausibly associate all of my symptoms with anxiety, I immediately felt better. I still have a few lingering symptoms that are obviously caused by poor posture and too much time on the PC, but I have experienced those before, and will address them with massage and PT.
It blows my mind how debilitating anxiety can be. Looking back, I can clearly see that I was having panic attacks caused by snowmageddon PTSD, COVID, work stuff, relationship drama, and a host of other "between the ears" baggage. I intend to get some professional help with dealing with anxiety in general, but just recognizing it is a huge part of the battle.
I'm more than a bit concerned that none of the professionals in my healthcare circle even suggested it. If my sister hadn't mentioned it to me as something I might want to address at some point, who knows how long I would have gone down the wrong path, continuing a life with no quality whatsoever.
Don't live with constant doom and gloom thoughts. It will eat you up eventually.
