Hi Tarabee,

Some of the symptoms you describe are associated with TOS - Thoracic outlet syndrome, especially the tingling in your ring fnger. TOS can go hand in had with other spinal issues. I have TOS as well as a subluxed c6 disc.

I encourage to take a look at the TOS forum. If you do have any indications of TOS, lifting that amount of weight wi not good.

Also you have to be very careful with PT because it can aggravate the situation if not specifically tailored. Many therapists are not properly trained to deal with it and make things worse.
