May need aggressive antivirals and advanced pain killers
Hi! Welcome to HealthcareMagic. Thanks for sharing your concerns with us. We will try to help you in the best way possible. First of all, it's sad to know what you had been going through lately.
Based on the history you have shared, it does seem like shingles but involving multiple dermatomes or areas or different nerve routes at a time is usually rare. Xrays of the cervical spine
with your current symptoms should also be done to look for any signs of vertebral
structural compression on nerves leading to numbness etc.
Antivirals like acyclovir
if started earlier are shown to be beneficial but the dosage is quite high and I am not sure that you are getting the required dose.
If numbness is increasing other causes of nerve damages should also be considered but if the rash is expanding too, it may need topical antivirals as well as aggressive painkillers like tramadol
along with nerve pain
suppressants like Carbamazepine
etc along with Gabapentin
that you are already taking.
If still the pain is not getting controlled, local painkillers patches or nerve blocks may also be needed.
Wishing you a speedy recovery.
Hope to this has answered your query. If you have any more questions please feel free to ask.
