### input:
Hi, I am 39 years old and after having an MRI scan, it was confirmed that I have a 4mm tumour in my pituitary gland. I have been taking quinagolide (75mg daily) since Dec 2010. My prolactine levels have returned to completely normal and I have now had my 6th period, which is great news as I am trying to get pregnant. I have since lost 3.5 stone in weight to help this process and improve my overall fitness.   In the past 3 weeks, my finger tips have gone numb (including thumb and pinkie finger) 3 times. This starts in my left hand, then shortly goes to my right hand. It lasts for between half an hour to  couple of hours at a time. I have an appointment with my consultant in a few months time for a check up, but am concerned about this numbness (with pins and needles sensation). Is this connected with either the tumour or the drugs and shall I try and get an appointment set up for an earlier date? Any advise would be greatly received.  Kind regardsMichele

Hi, Thanks for writing in. Pituitary tumor measuring 4 mm a too small to cause symptoms. However, it will help to get examined clinically and if required then please get a review MRI scan done. Quinoline causing numbness is rare however the use of other medicines is important to discuss with your doctor. It is important to know if you ever had symptoms due to cervical spine degeneration. The nerves supplying fingers originate in the neck spine and if there is any degenerative process in the spine then it might lead to numbness and tingling in the fingers. Avoid sudden movements of the neck and do not lift heavy weights. Please do not worry.
