Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.F.
You are asthmatic, 43yrs, 90kg weight, you had rapid heart rate
, and painful knees, these all seem to be due to the drugs you use for the asthma treatment.
Solbutamol and some other bronchodialators used for asthma have a potent cardiac stimulant action, so far you are compramised with the drug, recently your resistance has come down, or the dose you are using must have increased, hence causing tachycardia
You comes under over weight, the steroids
, and other drugs might be causing Osteo poresis causing joint and nerve
I advise you to consult a physician for diagnosis and treatment. Dont worry you will be fine.
