I am currently undergoing herceptin  injection probably just another 2 or 3 more injections left.  I am now in and out of emergency hospital but could not find anything wrong with me.   They perform ecg and chest X-ray every time and apparently my oxygen levels is okay and my lung is clear.   Here is the problem for the last 2 weeks I have been experiencing tightness in my chest and very difficult to breath then I feel like a blockage in my throat .   I am losing weight so fast, losing my appetite, hard to swallow and more difficult to breath with a full belly.   Ever episode I feel dizzy and a bit nauseous and with tingling on my right chest  neck extending to my right eyes and head.  This is now a daily occurrence.  Each time I visit my medical centre they come with different conclusions, panic attacks, asthma and I tried treating them as they prescribed me but nothing seems to address the issue.   I really don’t know what to do now.  Maybe tell my cancer doctor to stop the treatment for now.    I have been seeing cardio but result is saying my heart is normal.   I reported the tightness in my chest so I am having CTCA scan next week for now I have just to wait and suffer, in the meantime I was prescribed a diazepam to cope while waiting for the procedure.   I s there anyone experiencing something like this.   I am so desperate for any help or opinion of what maybe is going on with my body right now.   I am so losing confidence in the health system at the moment.   Thank you so much and sorry for venting.   Love to all.  .    ...
