Could Red Bumps On Penis And Sore Throat Be Due To Smoking?

Hi, I had small red bumps on my penis right under the head for about a week. there was no discomfort, itching or burning. They went away on there own and there are no scabs or crust, just a small red spot where it was bumpy. It was also mainly on the left side of the penis and occured after I had a tiny cut from friction during intercourse. now that it is completely healed up (seemingly) i have a slight pressure or tingling sensation in the penis that is barely even noticable. I also have a somewhat sore throat and cough ( I have been chain smoking because of the stress, possibly the cause?) I am uncircumsized and have recently changed body wash and used a new lube.
