increased dosage of ppi, woke up with numbness in left hand

wondering if this is related. been on lansoprazole 30 mg just over two weeks and on second day of doubled dose of lansoprazole, now at 60 mg/day (not taking any other meds) and I woke up in the middle of the night with numbness in my left thumb and a few other fingers on that hand. I almost want to say I feel a slight bit in the left side of my face and faintly in the right hand, too but it's hard to tell. thought it could have been from sleeping on it wrong somehow but I moved around, it's morning now and it's still present.

fyi: I have had intermittent periods of this when I've sat with my arm on a desk a certain way, but it hasn't happened for a long time.

kind of concerned about taking more, but can't ask the doc as he's not in on sunday.
is this a side effect?
what's the proper course of action here, call pharmacy?

hmm some conflicting info...

pharmacist says no it's not a side effect of the med, but I find a few places where it's mentioned online. one site mentions it like it's no big deal and the other makes it sound more serious.  https://ssl.adam.com/content.aspx?productId=47&pid=47&gid=601569&site=welldynerx.adam.com&login=well1815

Hi,
Parasthesia may occur as a side effect of lansoprazole. If it is persistent, then you may have to stop the medication and consult your doctor for an alternative medication. "

very confusing. pharmacist says no, one site says yes but no big deal and the other says seek immediate medical attention.

grrr. don't know what to do.

thanks for your comments.
I was thinking of taking just 1 pill today rather than 2 but I'm hesitant. I hate to stop completely because this solid food dysphagia is really getting me down.

you mean skip them altogether for one day and talk to the doc tomorrow?

I'm a long time vegetarian so b12 could be low, but I've been drinking 3-4 ensure a day since I can barely eat solid food. so I figured I was still getting enough.
