Headache and Migraines Forum - General Reasurance Regarding Head Pains

I've just come back from holday from florida, although not a relaxing holiday, very enjoyable. (living in england)

i've returned to work today worried about the things that are happening to me, i've read the forum and it seems I have similar symtoms as icepick headaches. I've had the for around 6 months on and off, maybe once every 2 weeks, the sharp pain lasts for approx 3 seconds at around 3 minute intervals for around 30 mins (hope that makes sense) I may get these sessions 3 times a day, I do suffer from the occasional migraines, real bad ones where I have to bed myself to get rid of them, these have also increased over the past 6 months.

The main worrying factor is that these pains have gotten worse over time as has my memory loss... I have short term memory lose, one particular occasion, my daughter asked me for a bowl of cereal, I went to pour the cereal, found there was no clean spoons, washed up all the pots and cutlery, turned and walked out of the kitchen forgetting the cereal, only when I looked at her and thought gosh cereal!!, she didn't have to say anything just looking at her reminded me of the original job I was inteneding to do.... Work is also suffering, I work with computers and I support a site of 100 people, users call me and say they have a problem, I put the phone down finish what I was origianl doing and totally forget about that call...... Another example is that I love rollercoaster rides, I went on quite a few in florida and people are asking me, did you go on kracken or dueling dragons I said, think so, I couldn't picture or remember what they were called...
Not sure whether this counts suckers term memory loss or just plain lack of concerntration but it's happening more and more.

As i'm typing this i'm expereicing these sharp pains, i'm under no stress at home or at work or else I would put it down to that.....

Please help to re-assure me that these are common everyday symptoms, hopefully you can but if I need to speak with a doctor then so be it tell me, i'm worried for myself as well as my family.
