Hi! I do appreciate your apprehensions regarding your symptoms. On net it is very difficult to assess the cause but I am glad you are undergoing the EMG/NCV test. This would assist in diagnosis. However entirely based on your post I can make some suggestions which you can discuss with your treating doctor. Muscle twitches can be due to muscle strain caused by either wrong posture or by repeated use of muscle. So if you have a sitting job and sit for long hours in a position then this can restrict blood flow to muscles and this can cause twitching. Getting up in between and stretching your muscles walking about a bit drinking water in between and eating fruits may help regain the water and electrolyte balance of the muscles and aid circulation. This may lower or complete erase the twitches. Prolonged sitting can also cause compression of lower lumbar and sacral spinal nerves and this can also contribute to twitching. Also since you have straightening of spine and flat foot the weight bearing is often not correct and this puts pressure on the spinal nerves. A MRI of the lower spine and the EMG/NCV test you are about to have will diagnose or rule this out. With pain going down the leg even if MRI is clear there is a chance that you suffer from radiculopathy (pain numbness tingling twitching etc in various combinations) of lumbarcral nerves. Since you have straightening of spine and flat foot it causes wrong weight bearing and puts pressure on the joints of leg as well. Hence it is important to show your knee to an orthopedic specialist since you feel that the knee cap is becoming loose. If you suffer from varicose veins or deep vein thrombosis or atherosclerosis then this can affect the blood supply of legs and cause twitching. The twitches will become more evident after prolonged sitting or standing. This can be diagnosed or ruled out after dopplar studies of the blood vessels of leg. Anxiety and caffeine too can be the cause and cutting down on caffeine can be of great help. Anxiety can be controlled through meditation deep breathing exercises listening to music etc or through medications. Low minerals in blood peripheral neuropathy due to diabetes or thyroid disorders or due to connective tissue disorders (autoimmune disorder) can also cause twitches. Other than this twitching can be a part of benign fasciculation syndrome however this would cause on and off twitching that is usually unrelated to posture. Since you feel the symptoms more when you lie down or are seated for long chances of anxiety a nerve compression or a blood vessel problem are more. However please discuss all this with your doctor. I sincerely hope you will find this information useful in your journey towards better health. Hope you get well soon! Good Luck and take care!
