Under Treatment For Radiating Pain In Chest And Neck, With No Relief. What Do The Varied Symptoms Suggest?

Dear Sir,

I have been experiencing pain (radiating to left chest , left hand , left side of stomach and sometimes to left leg) for past two weeks .BP (130/90mm) ,ECG were normal when consulted a general physician.

I was told that the neck might have got sprains and was advised to take up IFT -in a physio-centre and was given general pain killer . Iam an working professional and I am really disturbed by the pain and radiative pain (not really a pain , but some sort of tingles) in hands .I was suggested to consult an ortho by my physiotherapist . consulted an Orthao , Neck LT was x-rayed and i was told that there are no problems in relation to neck bones .MY doctor prescribed me a muscle relaxer ( FLEXURA- Metaxalone 400 mg) and was advised to take IFT along with ICT ( traction therapy) .

Again , visisted my general surgeon , who stopped flexura and prescribed me ( NUROKIND G 100) Gabapentin -100 + metaxalone tablet and ( NEORELAX-MR ) Thiocolchicoside 4mg, Aceclofenac 100mg & Paracetamol 500mg Tablets .
Iam continuing IFT+ICT till now .

My quereies are :

1.My neck and shoulder pain are still persisting .will there by any undetected issue in my neck bones ?like cracks or any dislocation or a bone pressing on a nerve ?

2.When the pain raidates down to shoulder and chest , iam over - excited , sweating starts and then shorteness in breath sometimes . Please explain reasons for shortenss in breath.Iam worried .

3.When the pain radiates down to stomach( tingling and vibrations) , sometimes iam urged to go for an excretion .Will it be a side effect of tablet ?

4.For the past three days , i have been expericening pain in my inner middle/inner ear (which i couldnot differentiate) .Is that an effect of existing pain or due to tablets ?
