I recently was diagnosed with a herniated disc between L4 and L5 (MRI). It started out with mild pain from my left Glutes to my Calf. The pain started about six months ago and would come and go but during the last three months the pain has become chronic to the point where I cannot stand or sit for more than a minute. I spend most of my time lying on my stomach or my my back. I have been taking about 600mg of Ibuprofen every three or four hours and it does relieve the pain as long as I do not stand or sit. I recently had a lumbar steroid injection through a pain management doctor and it seems to be helping but it has only been a few days. My concern is this. During the last 4 months I have lost a total of almost 30 pounds. I am 5 9 . At the time of the onset of weight loss I was 188 pounds, 12% BF and now I am under 160 and close to 9% body fat. I trained regularly at the gym(weights and cardio). Other than the sciatic nerve I do not fell physically ill, overly tired or have a loss in appetite. I have switched up my diet to omit inflammatory foods such as refined carbohydrates, red meat and foods high in saturated fats. I have been eating foods high in fatty 3 omegas, greens, fruit, clean carbs like whole grain breads and protein souses like yogurt, chicken and fish. My caloric intake has been around two thousand calories or less a day, possible close to 1500 calories. The reason I have not been eating more is that the pain to just walk into the kitchen and prepare meals is just too intense. The weight loss seems awfully rapid considering how sedentary I have become resulting from the sciatica. Should I be concerned?
