Thank you for your kind reply. I will certainly check the situation with my doctor as soon as I am back in town.
Hi!
Pain in the front portion of hip, thigh and knee can be due superficial nerve compression (lateral femoral cutaneous nerve), that comes from the hip area and gets pinched. This condition is called meralgia paresthetica and is often due to weight gain or wearing tight clothes and belts. Losing some weight or wearing loose clothes and belts often helps relieve the pain/numbness/tingling. Also injection of lignocaine (anesthetic agent) at the site helps. In your case you can apply a pain reliever at the site. Keep a hot water bottle/heating pad while sleeping and apply a local analgesic cream.
Other possibilities are vascular pathologies such as deep vein thrombosis and clots and will need a dopplar study. Peripheral neuropathies as in diabetes, hypothyroidism, Lyme's and lupus are the other possibilities. Do discuss this with your doctor and get yourself examined. Take care!
