What could be causing radiating leg pain and chest pain, which worsens while lying flat?

Hello doctor,

I am a 24-year-old female. I vape and have already been diagnosed with asthma, allergies, anxiety or OCD, and AVNRT. Currently, I take the tablets Luvox, Metoprolol, Loratadine, Singulair, Advair, and ProAir. Two months back, I started experiencing intense aches in my right leg and some shakiness and numbness at times. This has continued off and on since. At times, the pain spreads to my other limbs as well. I notice it is worst at night after a long day with a lot of movement or driving. I also had some issues with my bowel and bladder and stomach cramping or pain. Last month, I started experiencing intense pain or discomfort in my chest's left side, which has been pretty constant since. I cannot sleep on my left side, and if I lay that way, I start having heart palpitations. I also have to sleep at an incline. Laying flat hurts my chest and makes me feel short of breath. What has been tested: MRIs (magnetic resonance imaging) of my entire spine and brain to rule out MS or any other spinal issues. Only problem found was a dilated right carotid artery, CT scans of chest and stomach - small kidney stone and ovarian cysts found, echocardiogram - showed mild pericardial effusion and mild regurgitation, countless EKGs - all mostly normal except some PVCs, comprehensive Metabolic Panels, glucose high at times (up to 150 mg/dL), sodium consistently slightly low, carbon dioxide consistently slightly low. CBC- HCB slightly high a few times, lymphocytes slightly low a few times, MCV consistently high (in low-mid 90s), PMNs slightly high, ANA blood test - negative, A1C - normal (not diabetic or prediabetic), CRP inflammation - normal range, magnesium - normal range but on low end, vitamin B12 - normal range, rheumatoid factor - normal range, C3 complement - high (66 U/mL), vitamin D - low (15 mg/dL) and urine Test. Despite low overall protein content in the urine specimen, small quantities of low molecular weight serum proteins are noted. Albumin and tubular proteins compose the majority seen. No M proteins are observed. Pattern is consistent with increased glomerular permeability. Microalbumin - high (12.3 mg/dL), Protein - high (38 mg/dL). Please help.
