About four weeks ago, I went to see my doctor with the complaint of neck pain and regular headaches. He told me that a muscle leading from my neck to my head (on the left side) was most likely the culprit, and prescribed me a gel ointment and pain killers.
After that the regular headaches ceased, however, I was still having trouble with my neck, in terms of minor pain and stiffness. I have to lay a certain way in bed; otherwise I wake up stiff and uptight the next morning. But yesterday, those pains got much worse.
Without warning yesterday morning, I found myself getting incredibly stiff, to the point now where I'm unable to twist my neck to the left. The pain has also spread to my left shoulder and left upper arm. I couldn't sit up in bed this morning, until I turned on my left side and pushed myself up with my right arm.
I'm also having difficulty taking a loud, and my chest feels very caught up and heavy. My voice turned hoarse and I find myself speaking in a whispering sound, with a kind of burning sensation in my throat.
I'm a 19 year old female, with no recurring health problems. I don't drink or smoke and I'm very active and exercise regularly. Can somebody please give me some guidance as to what I can do, or what this might be?
