Blood oxygen symptoms and conditions

I have been on Levaquin for 5 days and have had an ache and tightness in the back of my neck since the first day. I have slept very poorly for the last three nights and over the last two days have developed significant chest pain..feels like the muscles in my chest and upper abdomen are in a constant contraction. I went to my internist yesterday thinking it may be an unfamiliar type of asthma attack. I used my inhaler on the way and blood oxygen was fine when I got there but the chest pain continued. I was given a chest Xray and an EKG, both of which were fine. My doctor did not feel that it could be the Levaquin and advised me to continue it. The contractions in my chest have continued, almost crushing at times. The neck pain has been continuous. I am stopping the Levaquin and willing to risk having the infection return.

I am 21 years old and my doctor prescribed me 20mg of Adderall to take twice a day. I've been taking it for about a week (only in the morning, I'm still too wound up to take it 4 hours later!) and I have already lost 10lbs. Also I've been having trouble breathing deeply, chest pain, tingling in my arms and legs, and no appetite whatsoever. Are these symptoms normal?

I have been on Yasmin for 2 1/2 years - and I always thought it was a blessing. I had very heavy, irregular periods before Yasmin, and now they are light and regular. The only thing that showed up on a test during the first year was a slightly higher triglyceride level, but it was still healthy.

However, last December I had what I thought was a heart attack. I went to the ER with palpitations, and they told me that I had high blood pressure, pulse, and low blood oxygen. After sitting in ER for about 30 minutes everything went back to normal, they said I had acid reflux and prescribed medication for that. The problems never really went away, and I have been to see my doctor at least once a month with different symptoms all the time. Before this I only went to the Dr once a year for my pap - I never got sick! Ever! She told me it was stress and anxiety, and didn't even look into anything else even though I insisted it had to be more than that. Every time I go to see her my blood pressure is always normal, as is everything else.

Sometimes when I am sitting at my desk at work or lying in bed reading I will start to panic for no reason at all and feel like I can't breathe, when if fact I have no problems breathing at all. I also get colds and allergies when I never had these problems before.

I'm not overweight, and I do cardio exercise everyday with no side effects so the Dr's rule out any heart problems. I never thought to blame Yasmin for my problems, and maybe I should make a switch to something else.

Has anyone switched to another BCP with better results?
