Hi, Thanks for your query. Possibility of compression of nerve root in spine, leading to tinglling sensation in your thighs radiating to feet. I will advise you to do MRI spine I advise my patient’s analgesic and neurotropic medication like pregabalin, you can consult to your treating doctor and do required investigation. Till time, avoid lifting weights, Sit with support to back. You can consult physiotherapist for help. Physiotherapy like ultrasound and interferential therapy will give quick relief. Another possibility of lumbar canal stenosis which will be ruled out on MRI. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
