A month before she use to walk every morning for 1 hour for months problem started when she started running for 5-10 min daily one day her right leg nerve pinched after that this sort of problem started and now if she walk a little like 15 min she feel tired,tingling in feet pain in arms ad bloating in stomach area. She had loss weight after lockdown we thought it may be thyroid but we had done test for it and it's not thyroid. Maybe her diet since she had only 2 chapti and dal, Vegetables.
