I havent had a general anesthetic since Ive had this illness but I got a SEVERE reaction from a local one the dentists use. Lidocaine
http://en.wikipedia.org/wiki/Lidocaine.. I'd been given the it with the adrenaline added into it as it is often done (one can request this without the adrenaline).
I only found out after my bad reaction that its advised for ME people not to have anesthetics with adrenaline in them like this one. The reaction it gave me was intense pain in the area in which I'd been injected (roof of mouth) for several days (like as if someone was drilling me) and it also affected me majorly in a neurological way... I went into severe jerking, was left unable to walk, tremoring and almost had a full seizure cause of that dentist injection. I couldnt leave the dentist for almost an hour after the procedure as I couldnt walk on my legs (We almost rang an ambulance.. something I really hate to do)..
(I'd had my wisdom teeth taken out during the procedure but the big gaping holes in my mouth were nothing compared to the pain from where this anesthetic had been injected. I'll rate getting my wisdom teeth out and the huge holes left as 2/10 for pain but the injection site an 8/10 with pain). I think it would kill me if a doctor gave me this to "numb" a bigger area.. ironic when a numbing drug causes almost unbearable pain.
Wikipedia says of side effects for this anesthetic are rare but also does say "Systemic exposure to excessive quantities of lidocaine mainly result in
central nervous system (CNS) and
cardiovascular effects – CNS effects usually occur at lower
blood plasma concentrations and additional cardiovascular effects present at higher concentrations, though cardiovascular collapse may also occur with low concentrations. CNS effects may include CNS excitation (nervousness, tingling around the mouth (also known as circumoral
paraesthesia),
tinnitus, tremor, dizziness, blurred vision,
seizures)"
So it seems as if my body (which also has MCS) reacted to it very unusually with it in a dental injection getting the same kind of affects as if one who had a systemic overdose of it. If yo have ME pay heed on the warnings put out by ME specialists on what ones to avoid, its not nice finding out this the hard way.
My ME started out with viral symptoms and what appears to be a reincurring virus which happened over and over..
