Thanks for posting your query.

I understand you are worried about feel “falling asleep” and concerned that it may be due to blood cutting off or quadriceps work out. I shall try to give you some suggestions to guide you with this issue.

Sitting down position is unlikely to cut/compromise blood circulation unless and until there is an underlying problem described as “peripheral vascular disease” (PAD) in your blood vessel. It is very less likely for peripheral vascular disease to be present at such a young age. If it is present it may be because of the presence of the same risk factors that cause PAD in older individuals: smoking, diabetes, high cholesterol, high blood homocysteine, and a family history of PAD or coronary heart disease.

Regarding quadriceps exercises, until and unless there is trauma to the muscles during exercise which causes any nerve compression, exercises also cannot cause such symptoms.

“Falling asleep” sensations in the feet/ legs are called parasthesia in medical terms. Numbness and falling asleep are abnormal sensations that can occur anywhere in your body, but are often felt in your hands, feet, arms, or legs. It can be associated with metabolic conditions like diabetes, hypothyroidism, vitamin B12 deficiency; peripheral vascular disease; neurological and spine problems causes malnutrition and rarely motor neurone disease or autoimmune disorders like multiple sclerosis or lupus erythematosis.

Based on your description metabolic issues or Neurological especially spine conditions are on cards. However a diagnostic evaluation by a competent physician is warranted to rule out other possibilities. If I were to be treating you, I would like to get your blood sugar and thyroid hormones levels tested and suggest you vitamin - B12 supplements for some days and see if the symptoms improve. Foods XXXXXXX in vitamin B 12 like mutton, liver, chicken and other non vegetarian food can also benefit you. If the symptoms persist then go ahead in getting you investigated to rule out other possibilities. Blood tests, spine scans as well as Doppler scan of peripheral vessels are entailed.

I understand you would be worried with the symptoms happening. But I feel you should be alright soon with the above suggestions.
