Could be due to a fungal cause
Thanks for asking on HealthcareMagic.
I have gone carefully through your query and understand your concerns. It seems that the itchiness on your forehead could be due to a fungal cause.
I would insist you to apply some antifungal cream or lotion like clotrimazole
topically (OTC). In addition, I would insist you to take some antiallergic like cetirizine
tablet (OTC) once daily for the next few days.
Regarding the tremors, you need to be investigated. Getting your blood tested for thyroid
profile and fasting blood sugar would be the first steps. Get them done and upload the reports and I would guide you accordingly.
Let me know if I could help further.
