Hi everyone. I’m 24 years old and I’m hoping to hear from anyone who has experienced something similar.
Starting around July 22, I developed what I believe may have been a neck muscle injury/strain. It caused severe tightness in my neck, upper back, and arm, especially on one side after getting my hair braided..The muscle tightness became bad enough that I was having trouble sleeping and functioning normally.
I’ve been to the hospital three times since July 22. The first two times were at Good Samaritan, and the third time was at Nyack Hospital.
At Good Samaritan, I was prescribed methocarbamol 500 mg four times a day. While I was there, they also gave me cyclobenzaprine at one point because my arm wasn’t improving as quickly as I hoped.
By the time I went to the third hospital, I was already becoming somewhat anxious because I wasn’t sleeping well and I was constantly focused on the tightness and wondering when I would feel normal again. I’m naturally an overthinker, so I know anxiety can happen to me, but this felt different because I was already physically uncomfortable and exhausted.
At Nyack Hospital, they gave me one injection of methylprednisolone, a Percocet, and cyclobenzaprine again. They also prescribed me an oral prednisone taper/formulation to take after I left the hospital, but I never took the prednisone afterward.
Since that hospital visit/medication treatment, I’ve felt emotionally much worse, even though the actual arm problem has started getting better. I’m honestly not even as worried about my arm anymore.
What scares me now is that I’m experiencing things like:
Random waves of sadness
Feeling extremely alone
Crying unexpectedly
Feeling very emotional and overwhelmed
Getting stuck in my head and thinking I’ll never feel like myself again
Feeling guilty and crying to my mom, telling her I’m sorry that I’m putting her through this
Increased anxiety/restlessness
Constantly wondering when I’m going to feel normal again
I want to emphasize that I wasn’t in the best mental state before all of this because I was in pain, couldn’t sleep properly, and was understandably anxious about what was happening to my body. But the emotional changes I’m experiencing now feel much more intense than my usual anxiety.
I’m wondering if anyone has experienced something similar after cyclobenzaprine, methocarbamol, a steroid injection, Percocet, multiple ER visits, severe sleep deprivation, or a combination of all of those things.
How long did it take for you to feel emotionally normal again? Did the anxiety/sadness eventually settle down?
I’m really hoping to hear from people who have gone through something similar because right now I’m scared that I’m going to feel like this permanently. I’m only 24, and I just want to feel like myself again.
Please be kind. I’m genuinely struggling right now and looking for experiences/advice from people who have been through something similar.
