Hi there ~
I understand your concerns. Heaviness in chest, wheezing
and pin prick rashes are signs of an allergic condition and I hope you have started treatment like you mention in your description of the issues. I also think that you should start to take medications to help with the neuropathic issues. Consult your doctor for the rashes that seem to be spreading and using pregabalin
to help with the neuropathy.
I hope this helps. Take care! Have a lovely day!
