Hi welcome to HCm I have gone thru your query rgarding sharp pain in the right temple after cardio workout It is a matter of concern . Dear for your info , starting any vigrous work out after a long gap can be hazardous and can cause various symptoms . The combination of elevated blood pressure, heart rate, thickened blood and constricted arteries can result in a devastating surge of blood attempting to enter the brain, forcibly expanding the arteriole walls and putting pressure on the meninges. To avoid exertion headaches during high intensity training sessions, build a solid cardiovascular base-- be hydrated, breathe correctly, and maintain a neutral spine. Also, consider performing the larger compound leg movements at the beginning of the workout. Leg movements are inherently heavy, taxing exercises . Once an exertion headache occurs, STOP. Do not attempt to push through the rest of the training session, it will only worsen the headache and the duration of symptoms . Start from Pranayam - Deep Breathing , Anulom Vilom ,Bharamri , Kapalbhaati , Pranayam help to have control on your breath and strengthen heart and can gradualy increase to stronger work outs . Rather than ignoring this symptom and powering through the pain, consult your doctor to rule out serious causes. Take Homeo pathic Arnica 30 dose in then morning & evening / 3 days Always remember, if pain is severe or incapacitating, please see your doctor / professional Hope this helps solves your query .Take care .All the best .Get well soon Don t hesitate to come back if have further query .
