Hi, I am 18 years old and I expierenced a asthma attack today that sent me to the emergency room. I was having pain in both my calfs during the attack and they told me it was from low oxygen levels in the blood due to the quick heavy breathing and that it should go away in a couple of hours. I was told this at 9:30 in the morning, and it is currently 6:30 at night. I am still expierencing pain in my calfs, a tingling feeling in both knees, and some new pain in my thighs. There is also a discomfort feeling, painful from time to time, where I have been diagnosed with tendinitis in my left elbow. I haven t had problems with asthma before like this, and have had no past medical issues. Is this normal for the leg pains and the pain in my elbow to still be there 10 hours after the initial start of the attack? Also, when I stand, I start to feel weak and a little dizzy but am fine when I am sitting down.
