Hi, ! First, I am so sorry you are still experiencing potential reactions to your procedure. Has your doctor had any helpful input for you? It's not unusual to experience issues following the procedure, especially headaches. However, it's not as usual to be experiencing symptoms months later. It *can* happen, but it's definitely not the norm or the desired outcome.
Frankly, I didn't find much along the lines of helpful tips for you. The main recommendation was to report continuing issues to your doctor, which it sounds like you may have done. I know. That's not the kind of input you were looking for here and I'm sorry about that. Many medical sites recommend contacting the neuroradiology team that performed the procedure, so if you haven't done that, you might try that.
So, you're not alone in this! You're in a smaller group that experiences lingering issues following a lumbar puncture, but you're not the only one.
