trouble breathing due to methadone withdrawal?

[Hecticus]

I have been doing methadone in recreational doses 1-2 times a week for months now. I have what feels like a pinched nerve atm in my left upper back. This started up with my breathing awhile ago but has gotten worse from gym. Seeing as I havent been a week without a dose ive never had any symptoms manifest.
I feel like I physically cannot take a deep breath, its been 4 days since my last dose.
Does anyone else get this? Maybe im obsessive but fuck its annoying.

It could be anxiety. But if you're still feeling it for a long period of time or it gets worse then see a doctor to be safe.
