for anyone who has these, it could be any medications you're taking or have taken, even if you used it occassionaly.
all medicines have it's list of side-effects, sometimes you'll get nothing but sometimes you will.
i've just found this out (again) because i have 3 days long numbness & tingling in my left pinky finger & on 1/2 that side of the hand, & worse yet, it keeps trying to spread onto other fingers & up the arm as well. then i look on this website & found out medications can cause this. well, i looked it up & the medication for menopause has done me in AGAIN (this isnt the 1st time!). Premarin has this as a side effect so now i have to stop using it at this dose. as a note, i have to type this being careful not to involve the left hand--not easy to do! anyway, premarin comes in a dose which is 1/2 of this dose so hopefully that will rid it--if not, i'm not taking it anymore & will use the herbal supplements i bought. a little history, when i said premarin has done it to me again, i meant i had to have the dose cut in half back on 3-1-07 because the side-effect of frequent vomitting was driving me nuts--i was puking about 5 times a week, then when the dose was cut it stopped & hasnt returned, but now i have this (when will premarin stop getting me?!). also forgot to say, this dose of premarin i use now is also giving me other bad side-effects: swelling & fluid retention of lower legs thats getting worse, borderline high blood pressure, TMJ-like symptoms where the left jaw joint aches bad & radiates into the ear--this hurts so bad i literally scream out in pain & the only way to stop most of it is to stay medicated on ibuprofen & tylenol all at once!
so, my advice is, take the side-effect of any medications seriously & consider it as the cause first. your medicine could turn out to be the problem like with me.
