Suggest Treatment For Extremely Painful, Tingling Toes In Left Foot
Subarachnoid hemorrhage origin very unlikely.
Detailed Answer:
I read your question carefully and I understand your concern.
Your hypothesis about the subarachnoid hemorrhage being at the root of your symptoms is a valid one. Considering the numbness was present on the same side, it could in theory be a remain of damage to the cortex. However the numbness would usually present in a more extended area than some of the toes, so to be honest I would consider that to be highly improbable. Also adherences created by the blood can create compression of the nerve roots which could cause similar symptoms, but you’ve had also had surgery to relieve your nerve roots and it would also show o nerve conduction studies so that is improbable as well.
In my opinion the cause is to be found in the arthritis which you report to have been diagnosed with which can also cause similar symptoms due to compression of small nerves by inflammatory changes. It would not be picked on nerve conduction studies due to that exam being able to evaluate only greater nerves.
So while post subarachnoid hemorrhage origin can not be completely excluded, I would consider them as probable factor only when all other causes are ruled out and in your case you have a much more common and sensible explanation like distal joint arthritis.

Detailed Answer:
I can fully imagine the distress you are in and the disability these symptoms can cause to your walking and daily activities. You seem to already have tried most of the drugs used for pain like antiinflammatories, acetaminophen and opioids (the codein present in Panadeine). I would give Cortisone some more time since you mention to have started it only recently, one would prefer to use as few drugs as necessary since all carry a potential of side effects.
If it is not enough, the only untried option is with medication for chronic neuropathic pain, which are either antidepressants like duloxetine, venlafaxine or anticonvulsants like pregabalin, gabapentin.
I hope to have been of help.
