Hi I quit smoking exactly 21 day ago. I had lots of problems since then. 1st day : light exercise in evening led to chest pain and in night breathlessness.Got panic attack as i was told by doctor.Breathlessness went away next day. Doctor(pulmonologist) ordered x-ray,PFT,blood test. Only thing that came out was high levels of IGE serum in blood, nearly 780 Iu. Then i was prescribed propranolol,epitril md 0.5 mg,gabapentin,pantocid dsr for a month. Well shortness of breath never happened after that. I visited the doctor again today after 21 days since chest pain was still present at many places mostly in middle and very light. He said it prescribed propranolol and pantocid dsr and a syrup for heartburn. When i do some light exercise the chest pain comes some times it comes without exercise too. Some times mucus but no color. Are these things normal and withdrawal symptoms? Is doctor going in right direction? He has some 20 years of Experience. I feel pain sometimes in my leg and stomach too. He says that there is nothing wrong with my heart or lungs, Its just muscles. I dont understand why there was high levels of IGE was found. And after light exercise like walking for 2 KMs there is chest pain. I smoked 5-10 cigarettes for three years. I have never experienced these symptoms before when i tried to quit. It went nearly 2 weeks without smoking many time when i was at my home in vacations.
