What Causes Severe Headache While Treating Occipital Neuralgia?
Read below.
Detailed Answer:
I read your question carefully and I understand your concern.
I wish you had provided some more info on the different medication you have tried, so that I do not risk repeating something which has not been successful. I will go on mentioning all the options.
I suppose you have tried over the counter anti-inflammatory medication. After that treatment for neuropathic pain is through anticonvulsants (pregabalin, gabapentin, carbamazepin) or antidepressants (amitriptyline, duloxetine).
The next step may be capsaicin or lidocaine cream or patches in the area. Usually opioids which you seem to be taking are the last resort in terms of medication.
In same cases a muscle relaxer such as Baclofen has also had some success.
In terms of other measures you may try there are of course massages, warm compresses and physical therapy, but I guess you are past that.
After those what is left are the more invasive measures which I do not know whether they are an option right now as you say not to be able to have nerve blocks right now. Apart from nerve blocks botox injections are also an option. Other options are radiofrequency, decompression surgery, cryotherapy. I suppose these are not here and now procedures if that was what you were looking for though, they must be scheduled.
These are for the moment the weapons we have against occipital neuralgia. I hope to have provided some option which you haven't already tried. I remain at your disposal for other questions.
