I would appreciate advice and comments please. I am a male in my 50s. I am overweight. I swim 30 minutes each day before work.
In the last few days I have been feeling, occasionally, a "pain" in the left side of my head. It is not a headache. It is not really unpleasant. It is difficult to describe. It almost feels "spongy". I have never suffered from headaches. It occurs three or four times per day and lasts for about 30 to 60 minutes. The pain / feeling seems to centre on a line from just above my left temple to just behind the top of my left ear. So the area affected is about three to four finger widths in size. Nothing else is affected. Can anyone advise why this might be occurring? Thank you in advance to those who kindly respond.
