The last 5 or 6 days I have felt different. I had lower left back pain for a couple of days and I tried to pick up sticks in my yard from a recent ice storm. I could only work about 45 minutes to 1 hour because I was out of gas. I was exhausted after that time. I went back out 4 times and still did not get all of them picked up. I came back in the last time and it took me an hour to warm up. Since then I have not had an appetite to speak of and I have had real bad night sweats. I am diabetic and I have high blood pressure and high cholesterol. I take Lanus, Januvia, Lovastatin, Furosemide, Ranitidine, Amlodipine Besylate, Pantoprazole, Metroprolol Tartrate. Omeprozole, Lisinopril HCTZ, Metformin, Potassium Chloride, Co Q 10, Vitamin d-3, B complex with C, Vitamin B-6, Multi-Vitamin, ginger Root, Viamin C, Fish oil, Vitamin E, Motion sickness pills, and Iron. I thought I was having a kidney stone and for about three days my urine was very very yellow. One time it was dark in color almost brownish. My back has not hurt only the two or three days but I just can't seem to shack this loss of appetite and I have slept a whole lot during the last 5 or 6 days. I worked at my job for 8 hours on Thursday and Friday. With my rotating schedule I had Tuesday, Wednesday, Saturday and Sunday off. What am I experiencing? I thought at first it was a kidney stone but a friend who had one said he thought it was a pulled muscle in my back. I also thought maybe it was side affects from the Lantus but I have been taking Lantus for 6 months and I experienced some of the Lantus side affects at the beginning of treatment but none since. What could it be?
