I started Levaquin 500mg 5 days ago for bronchitis/pneumonia. Well today I did not take the medication because within the hour after taking it I have a tuff time breathing when moving around. I now have upper front pain in my thighs and around my hips, I have a feeling of heaviness and tightness across the breast area of my chest, my throat has this sense of fullness that comes and goes and I have a uncomfortable feeling in the base of my skull, my fingers at times feel like the circulation has been cut off and then it goes away, my heart feels like it is racing or not beating right. I have this thought in my head the last 2 days as to whether I should go to the emergency room because I am not sure now if it is my heart.
