I do not have a sore throat, my throat seems to tighten up at times, it does not hurt to swallow & my voice is hoarse, this has been happening for 3 w?

Worrisome. If this is really a 3 week emerging problem the possibilities are worrisome. This could be simple, like vocal cord dysfunction, where they spasm unpredictably. It could also be an emerging issue deep in your airway. A consultation with an ENT should be arranged this week or as soon as you can get in.
Need evaluation. Your PCP may refer you to an ENT specialist or get CT scan of your neck.
