I have recently been experiencing pain that comes and goes on the left side of my head at the back of the ear. I also experience a bit of tingling .It did go away for a few days but its back again. A few months ago I had a mild heart attack and had all the test possible and they said no damage was done. I also had brain scans to se if I may have had  a clot . RegardsRosie
Hi, Welcome to Chat Doctor forum.  As you describe it appears to be the sinusitis, or migraine, probably subclinical, and exacerbate when ever there is cold.  I usually prescribe to my patient with such symptoms lifetime, phenylephrine HY Chat Doctor.  Take more of green leafy vegetables, pulses, and sprouts and Protein rich foods to help the recovery.  Wishing for a quick and complete recovery, Thank you.
