I've had cough for about 3 months mostly at night, with Itching and tightness of the chest, coughing up of colourless sputum, is it asthma?

Many possibilities . Including asthma but also GERD (gastroesophageal relux disease) or post nasal drip. As these other forms of cough can be notoriously worse at night related to how we are more predisposed to severe reflux (which csn even present only with a cough!) or post nasal drip based on how our anatomy changes with our body position. Sounds like you should review this with your doc.
Probable. It is likely that you have asthma but you really need to see a doctor to confirm the diagnosis and be treated accordingly.

No cough or sputum but I have a wheeze and tight chest. Pred. Value spirometry is 83%. Is this COPD or late onset asthma?

Other factors. Asthma is reversible airway obstruction that can start in adults. After taking several puffs of albuterol inhaler, there should be at least 12% improvement in fev1. While 83% falls within normal range, it is not likely normal for you if wheezing and tightness are present. COPD is from smoking and can show obstruction on lung function, but is less likely to be reversible like asthma. Read more...
Need more info. You gave predicted value but what was your actual value. By definition, asthma is reversable airway disease, i.e. Once you treat it, your lungs return to baseline normal. In contrast, copd, your airways will not return to normal but rather reach a lower than normal baseline depending on how severe you are. Thre are four leverl of disease and you get catagorized based on a lung function test. Read more...
More information pls. COPD patients typically will produce more sputum or mucus when they cough. Your symptoms may be either but without a history of smoking, asthma is more likely. Since you have had a PFT , asking for the FEV1/FVC ratio will help your physician determine whether there is a component of restriction as well. Read more...

I've had a fever for 2 days, a cough, tightness in chest, achy joints, coughing up sputum and it's difficult to breathe deep. Should I see a Dr?

Yes. From the Family Doc perspective, viral upper respiratory infections are much more common than bacterial. And they all present in similar fashion. Plus sputum color doesn't really tell us anything. So the reason I would recommend that you see your GP is b/c you're reporting difficulty breathing. That needs to be evaluated ASAP. Please don't wait to see if that will go away. Go to A&E if necessary. Read more...
