I'm a 21 year old female, 5'5", and 135 lbs. I run 30 minutes a day at least 5 days a week, and also do 20-30 minutes of muscle exercises 3-4 days a week. I have a history of neck and back problems. Lately, however, I've been experiencing a lot of muscle fatigue that seems strange. My whole body feels very weak and exhausted no matter what I do. For awhile I was only eating 1200-1300 calories, so I increased my calories to about 1500-1600 a day, but it has been over a month and I feel the same: very weak and exhausted, and in pain in my arms, legs, and shoulders. I also have massive headaches almost every day that last almost all day long. In addition, I often wake up in the morning with a numb body and tingling sensation in my face. I can move fine, but it just feels like something is not quite right. My violin instructor noticed a couple weeks ago that my forearms and hands seem to be swollen so she felt along some of the muscles, and it hurt very bad. I didn't even notice it until she pointed it out, so that's just another part of this whole problem. I've used tons of ibuprofen and ice but it doesn't seem to take away this constant pain I'm in. I'm trying to get into a doctor at my college, but it will take awhile because the wait list is so long. I hope someone can have some helpful advice for me soon!
