Is the heat felt the whole body or just in the head area? If just the head, which area? ie frontal, left / right or back brain's lobe. Does it start to occur when you are reciting some particular wazifah? if so, which particular wazifah is it ?s Does it occur in the morning or evening of your dzikir time or during both times ? Is it because of your imamah too tight ? Sorry for asking a lot of questions. You case just intrigue me... 8^) Alhamdulillah seems that extra darood and istighfar have a +ve effect. May ALLAH always protect and showers you with HIS bountiful blessings. nb: maybe you can try some ruqyah for headache too... see http://www.sunniforum.com/forum/show...l=1#post796944
